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..
How does and AC motor work?
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..
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.
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..
