How do capacitors work?
Capacitors are used to store electricity. In contrast to the usefulness of resistors, capacitors do not dissipate energy in their optimal form. Read more..

An AFCI is a type of circuit breaker that is designed to protect against electrical fires caused by arcing faults. Read more..
AFCIs work by sensing when an arc fault is about to occur and then interrupting the flow of electricity before the arc can form. Read more..
generators transform mechanical energy into electrical energy. The mechanism involved is similar to that of an alternator.. Read more..
An alternator is a device that creates alternating current by transforming mechanical energy into electrical energy. Read more..
Unlike an asynchronous AC motor, a synchronous AC motor rotates at the same speed as the frequency of the AC power supply. In order to achieve this, the synchronous AC motor must be synchronized with the power supply using a feedback system. Read more..
An induction motor is an AC electric motor in which the electric current in the rotor needed to produce torque is obtained by electromagnetic induction from the magnetic field of the stator winding.
Diodes are semiconductor devices that allow current to flow in only one direction, making them useful for a variety of applications such as rectification, voltage regulation, and signal modulation. Read more..
Rectifiers work by allowing only half of the AC cycle to pass through them. During the positive half-cycle, the rectifier allows electrons to flow from the negative terminal to the positive terminal. Read more..
A rectifier is an electrical device that converts alternating current (AC), which periodically reverses direction, to direct current (DC), which flows in only one direction. The process is known as rectification. Read more..
Some common applications of direct current include:
1. powering electronic devices
2. charging batteries
3. operating electric motors
4. welding metals

Direct current (DC) is an electric current that flows in one direction only. DC is the kind of current produced by batteries, fuel cells, and solar panels. Read more..
Alternating current can be dangerous if not used properly. For example, touching a live wire carrying AC can result in electrocution. AC can cause interference in electronic devices, which can lead to data loss or corruption. Read more..
Direct current (DC) is an electric current that flows in one direction only. This means that the voltage of a DC signal does not change over time. DC signals are typically generated by batteries or solar cells.
Alternating current, on the other hand, is generated by power plants and flows through the power grid to homes and businesses. Read more..
Alternating current (AC) is an electric current that reverses direction periodically. This means that the voltage of an AC signal also reverses direction periodically.
The frequency of an AC signal is the number of times per second that the current or voltage reverses direction. Read more..
The first step in knowing how to fix a broken light switch is being able to identify when one exists. There are a few telltale signs that a light switch may be broken, which include:
-The switch does not click when engaged.
-The switch feels loose or wobbly.

Ohm’s law is used in many branches of physics, including electricity, magnetism, and optics. It can be used to design electrical circuits, calculate power dissipation in electronic devices, and troubleshoot electrical problems. Read more.
Ohm’s law is used to calculate the current in a circuit.
For example, if you know the voltage and resistance of a circuit, you can use Ohm’s law to calculate the current. Read more..
Ohm’s law states that the current through a conductor between two points is directly proportional to the potential difference across the two points. In other words, the higher the voltage, the higher the current. Read more..
AC motors are more efficient than DC motors and can operate at higher speeds. Additionally, AC motors are less likely to overheat than DC motors and can be used in a variety of applications. Read more..
An AC motor works by using electromagnetism to convert electrical energy into mechanical energy. The alternating current creates a rotating magnetic field that interacts with the armature, or rotor, of the motor to create torque. Read more..
An AC motor is an electric motor that uses alternating current (AC) instead of direct current (DC). AC motors are more efficient than DC motors and can be found in a variety of applications, including fans, pumps, and compressors. Read more..
