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.

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..

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..

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..

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..

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.
