Question

3.When an alternating voltage is applied to a capacitor
A) A direct current flows in the circuit for a short time and then become zero
B) An alternating current flows in the circuit for a short time and then become zero
C) No current flows in the circuit D) An alternating current flows in the circuit​

Answer 1

Answer:

A) As we know by ohm's law V=IR When a short circuit occurs load gets bypassed (shorted) ie; R=0 Then I =V /0; Therefore ideally the current becomes infinite.

B) AC circuits exhibit characteristics which are exploited in many devices of daily ... in a dc circuit, current will flow for the short time required to charge the capacitor.

C) The current flows in the circuit for some time then decreases to zero. C ... a maximum value when the capacitor is charged to the voltage of the battery. D. An alternating current flows in the circuit ... No Signup required.
