Frequently Asked Questions
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..
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 are the benefits of AC motors?
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..
