Question

Name the device that will: a) permit flow of direct current but oppose the flow of alternating current.
b) Permit flow of A.C but not theD.C

Answer 1

Answer:

$b$is. your your answer

Answer 2

Concept

Electric charge that periodically reverses direction is known as alternating current, or AC. It might begin, for example, at zero, increase to a maximum, decline to zero, reverse, reach a maximum in the opposite direction, return to the initial value, and repeat this cycle indefinitely. The one-way flow of electricity is known as direct current (DC). DC power is best demonstrated by an electrochemical cell. Direct current can go through a conductor, like a wire, as well as through semiconductors, insulators, and even through a vacuum, like in electron or ion beams. It can also travel through semiconductors and insulators.

Explanation

a) A device known as an inductor allows the flow of direct current but resists the flow of alternating current.

b) A capacitor is a device that only allows alternating electricity to flow through it; direct current cannot.

Hence, inductor allows DC not AC while capacitor allows AC but not DC.
