Which of the following circuit component opposes the change in the circuit voltage ?
Correct answer: B. Capacitance
- A. Inductance
- B. Capacitance
- C. Conductance
- D. Resistance
Explanation
A capacitor opposes sudden changes in voltage because its current is i = C dv/dt, so an abrupt voltage change would require an unrealistically large current. Inductance instead opposes changes in current.
