Frequently Asked Questions
What is Ohm’s Law?
Ohm’s law states that the current through a conductor between two points is directly proportional to the potential difference across the two points. In other words, the higher the voltage, the higher the current. 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..
How do rectifiers work?
Rectifiers work by allowing only half of the AC cycle to pass through them. During the positive half-cycle, the rectifier allows electrons to flow from the negative terminal to the positive terminal. 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..
