Capacitor opposes change in

Electrical Engineering XYZ MCQs

Capacitor opposes change in:

  1. Current
  2. Voltage
  3. Both of these
  4. None of these

Correct answer: 2. Voltage

Explanation: A capacitor primarily opposes changes in voltage. It does this by storing or releasing charge in response to voltage changes across its plates. When you try to change the voltage across a capacitor, it either takes in charge or releases some, which smooths out abrupt changes in the voltage. This characteristic makes capacitors useful for stabilizing voltage and filtering out fluctuations in electronic circuits. While a capacitor does affect current flow as it charges or discharges, its primary behavior is linked to resisting changes in voltage, not directly opposing changes in current itself.
