A capacitance is a circuit component that opposes the change in circuit__________?
Correct answer: B. Voltage
- A. Current
- B. Voltage
- C. impedance
- D. None of the above
Explanation
A capacitor resists sudden changes in voltage because its current follows i = C dv/dt; changing its voltage instantly would require infinite current. An inductor, in contrast, opposes sudden changes in current.
