Instantaneous power in inductor is proportional to the
Correct answer: A. product of the instantaneous current and rate of change of current.
- A. product of the instantaneous current and rate of change of current.
- B. square of instantaneous current.
- C. square of the rate of change of current.
- D. Temperature of the inductor.
Explanation
For an inductor, v = L(di/dt), and instantaneous power is p = vi = Li(di/dt). Since L is constant, power is proportional to the product of instantaneous current and its rate of change.
