ELECTRICAL REVISION QUESTIONS AND ANSWERS.13
What is Current? - correct answer Electrical current is the flow rate of electric charge in electric
field, usually in electrical circuit.
What are the two types of Current flow? - correct answer AC and DC
What is alternating current (AC)? - correct answer An electric current that reverses its direction
many times a second at regular intervals.
What is an Ampere (Amp)? - correct answer A unit of measure for the intensity of an electric
current flowing in a circuit
What is a capacitor? - correct answer A device used to store an electric charge, consisting of
one or more pairs of conductors separated by an insulator
What is a circuit? - correct answer A closed path in which electrons from a voltage or current
source flow
What are the two types of ways current/voltage can flow in a an electrical circuit? - correct
answer In series or in Parallel (or a combo of the two)
What is a conductor? - correct answer Any material where electric current can flow freely
What is Direct Current (DC)? - correct answer An electric current that flows in only one
direction
What is Frequency? - correct answer The number of cycles per second. Measured in Hertz. If a
current completes one cycle per second, then the frequency is 1 Hz; 60 cycles per second
equals 60 Hz.
