If A.C. voltage is applied to capacitive circuit, the alternating current can flow in the circuit because__________________?
Correct answer: A. varying voltage produces the charging and dicharging currents
- A. varying voltage produces the charging and dicharging currents
- B. of high peak value
- C. charging current can flow
- D. discharge current can flow
Explanation
An alternating voltage continually changes the charge on the capacitor, producing alternating charging and discharging currents. A capacitor blocks steady DC after charging, but this changing voltage allows AC current to flow.
