What is a circuit?
Q: What is a circuit?
A: A circuit is a closed path that consists of circuit components in which electrons from a voltage or current source can flow.
Q: What are the two types of circuits?
A: Electrical circuits and Electronic circuits. Electrical circuits consist of electric components like resistors, capacitors, and inductors, while electronic circuits consist of electronic components such as diodes and transistors.
Q: What is the point where electrons enter an electrical circuit called?
A: The point where electrons enter an electrical circuit is called the "source" of electrons.
Q: What is the point where electrons leave an electrical circuit called?
A: The point where the electrons leave an electrical circuit is called the "return" or "earth ground".
Q: What part of an electrical circuit lies between its starting point and return to source?
A: The part of an electrical circuit that is between the electrons' starting point and the point where they return to the source is called an electrical circuit's "load".
Q: What are two forms of electricity used in circuits?
A: Circuits use two forms of electricity - alternating current (AC) and direct current (DC). AC often powers large appliances and motors and DC powers battery-operated vehicles and other machines and electronics.
Q: How can AC be converted to DC or vice versa?
A Converters can change AC to DC and vice versa. High-voltage direct current transmission uses big converters.
