Frequently Asked Questions
What is Ohm’s Law used for?
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..
What is an induction motor?
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.
What is an alternator?
An alternator is a device that creates alternating current by transforming mechanical energy into electrical energy. Read more..
What is alternating current?
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..
