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 an arc fault circuit interrupter (AFCI)?
An AFCI is a type of circuit breaker that is designed to protect against electrical fires caused by arcing faults. Read more..
How does AC differ from DC?
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..
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..
