Power transfer will be maximum when:
Correct answer: C. R = r
- A. R > r
- B. R < r
- C. R = r
- D. R = 1/r
Explanation
Maximum Power Transfer occurs when the resistive value of the load is equal in value to that of the voltage source's internal resistance.

About Maximum Power Output
Maximum power output describes the condition in which a source with internal resistance delivers the greatest power to an external load. The topic uses P = I²R and related circuit equations to show that maximum power occurs when load resistance equals internal resistance. This differs from maximum efficiency, which occurs under a separate condition.
