Electricity is one of the most important things in our lives. It powers our lights, appliances, and computers. It also helps to keep us safe by powering our security systems. However, many people do not understand how electricity works or how to stay safe around it. T
In today’s society, electricity is used in nearly every aspect of our lives. It is essential to understand how electricity works and how to safely use it. That’s why it’s essential to learn about electricity before knowing what are the two types of electricity so that you can stay safe and make sure your home is running efficiently.
Most people take electricity for granted and do not think about what it takes to produce the power we use daily. Electricity is a form of energy that must be generated and delivered to consumers through a complex network of power plants, transmission lines, and distribution systems.
Before learning about what are the two types of electricity, you must first know what electricity is. In this following article, you will learn about electricity and its kind.
What is electricity?
Electricity is a naturally occurring phenomenon that is used daily by most people across the globe. It is safe to say that electricity has become one of the most important aspects of our lives. But what exactly is electricity?
Electricity is the flow of electrons through a material. This flow can be harnessed and used for a variety of purposes, such as powering homes and businesses, running appliances, and even providing light.
While we often take electricity for granted, it is a very complex topic. Scientists are still studying electricity and learning more about how it works every day. However, there are some basic concepts that we do understand.
For example, we know that electricity can be generated in several ways, including through the use of batteries, solar panels, and generators. We also know that it can be transported over long distances using power lines.
The Two Types Of Electricity.
Electricity is a type of energy that flows between conductors, such as wires, to power devices. It is produced by the movement of electrons. There are two types of electricity: static and current.
| Static Electricity | Static electricity is an imbalance of electric charges within or on the surface of a material or between materials. The charge remains until it can move away using an electric current or electrical discharge |
| Current Electricity | An electric current is a stream of charged particles, such as electrons or ions, moving through an electrical conductor or space. It is measured as the net rate of flow of electric charge through a surface or into a control volume |
Static Electricity:
Static electricity is the result of an imbalance between positive and negative magnetic charges in an object. This charge can build up on an object until it is discharged or released. One way to discharge it is by plugging it into a circuit.
In 1752, Benjamin Franklin discovered static electricity while experimenting with a kite. He found that when the kite was struck by lightning, it created a spark of static electricity.
In 1800, Italian physicist Alessandro Volta invented the first battery. This battery could store static electricity and release it in a controlled way.
In 1873, English scientist James Clerk Maxwell published a theory that explained how electric fields could be generated by moving charges. This theory paved the way for the development of electronic devices such as radios and televisions.
Static electricity is an electrical charge that accumulates on the surface of an object. The charge remains on the object until it is discharged to another object or the ground.
Static electricity is created when two objects rub together and electrons are transferred from one object to the other. The object that loses electrons becomes positively charged, while the object that gains electrons becomes negatively charged.
The force of static electricity can be used to levitate objects, create sparks, and even cause fires. Static electricity can be dangerous, so it’s important to discharge any accumulated charge before handling sensitive electronic equipment.
Example:
- Photocopier
- Balloon Party Trick
- Charged Comb
- Doorknob
- Television Screen
- Winter Wear
- Nylon Clothes
- Rubbing a Rod with a Cloth
Current Electricity:
Dynamic or current electricity is defined as an electrical charge moving through space. It consists of electrically charged particles moving from atom to atom via conductors in an electrical circuit. The force responsible for this current is the electromotive force (emf) or voltage.
The invention of current electricity is one of the most important developments in human history. Without it, we would not have the modern world as we know it today.
Current electricity was first discovered in the late 18th century by Italian physicist Alessandro Volta. He found that when he connected two metals with a moistened paper between them, an electric current flowed between the metals.
In 1831, Michael Faraday discovered that when a wire is moved through a magnetic field, an electric current is produced. This discovery, known as electromagnetic induction, revolutionized the field of electricity. Faraday’s work paved the way for the development of the electric generator, which converts mechanical energy into electrical energy.
The first commercial electricity generation plant was built in 1882 in New York City. The plant used direct current (DC) to power 500 lamps in a nearby office building. DC is a type of electricity where the electrons flow in one direction only. However, it was quickly realized that DC had its limitations. In 1887, three engineers working independently developed a system that uses alternating current (AC). AC is electricity where the electrons change directions periodically.
Examples:
- Two Charged Conductors Separated by an Insulator
- Two Charged Conductors Connected by Metallic Wire
- All electric Gadgets.
What are the two types of electricity (current) and their implications.
Current electricity is the movement of electric charge. There are two types of current electricity: direct current (DC) and alternating current (AC). DC is a unidirectional flow of electric charge, while AC is a bidirectional flow of electric charge. DC is generated by sources such as batteries and AC is generated by sources such as power plants.
DC Current:
DC, or direct current, is the constant flow of electric charge from one point to another. DC electricity is produced by batteries, fuel cells, and solar panels, and it is used to power small electronics like cell phones and computers. DC can also be generated by large-scale power plants and transmitted through long-distance power lines.
Direct current (DC) is an electric current that flows only in one direction. It is produced by sources such as batteries, solar cells, and fuel cells and is also the form in which electric power is delivered to homes and businesses. DC can be found in many electronic devices such as radios, computers, and TVs.
DC is a type of electrical current, meaning it flows through wires to power electrical devices. The “direct” in direct current means that electrons flow in only one direction through the wire. Batteries are common sources of DC power. Solar cells and fuel cells can also produce DC electricity.
In the United States, most household appliances run on AC power. But many electronic devices use DC power. For example, radios, computers, and TVs all use DC electricity.
Pros:
- requires less conductor material
- free from the skin effect
- no capacitance in the DC transmission
- no inductance, phase displacement, and surge problems
- less voltage drop
- no stability and synchronizing problems.
Cons:
- commutation problems.
- DC switchgear has its limitations and they are also expensive
- Cannot be directly stepped up or stepped down for transmitting the power at high voltages and for distributing it at low voltages.
- requires extra equipment
Example:
- DC motor
- DC power inventor
- Charging batteries
- To get a constant magnetic field that can be used for an electromagnet.
- Networking Systems
AC Current:
AC current is an electric current that periodically reverses direction and magnitude. It is an alternating current. The waveform of AC can be represented via a sine wave. The time-averaged value of an AC voltage or current is zero. The RMS value of an AC voltage or current is what determines the amount of power it delivers.
AC current is an electric current that reverses direction periodically. The average value of an AC current over a complete cycle is zero. The RMS value of an AC current is equal to the DC current that would produce the same heating effect.
The most common form of AC current is sinusoidal, which can be generated by rotating a coil in a magnetic field. Another common form of AC current is a square wave, which can be generated using electronic circuitry.
While the direct current (DC) flows in one direction only, alternating current (AC) changes direction periodically. The standard AC frequency in North America is 60 Hz, meaning that the current alternates directions 120 times per second. European countries use a 50 Hz frequency, resulting in 100 reversals per second.
The main difference between AC and DC is that AC voltage periodically reverses polarity while DC voltage maintains a constant polarity. In other words, with AC there is constantly a changing magnetic field created by the flow of electrons whereas with DC there is not. The changing magnetic field of an AC current can be used to generate electricity while the constant electric field of DC cannot.
An alternating current (AC) is an electric current where the direction of the flow of electrons changes periodically. The frequency of the AC can be anything from a few hertz to several kilohertz. The most common form of AC is the main electricity that powers our homes and appliances.
Pros:
- electric power can be generated at high voltages
- AC voltage can be increased with the help of a step-up transformer or can be decreased using the step-down transformer easily and efficiently
- AC switchgear such as circuit breakers are cheaper than DC
- repair and maintenance are easy.
Cons:
- construction of AC transmission lines is more complicated
- requires more conductor material
- the effective resistance of the AC transmission line is higher
- continuous power loss
Examples:
- Generating DC
- providing electricity in Industrial Sector
- Hybrid and electric vehicles
