Frequently Asked Questions
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..
What is a diode?
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..
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 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..
