For maximum transfer of power, internal resistance of the source should be_____________?
Correct answer: A. equal to load resistance
- A. equal to load resistance
- B. less than the load resistance
- C. greater than the load resistance
- D. none of the above
Explanation
For maximum power transfer in a resistive circuit, the load resistance must equal the source's internal resistance. At this condition, the load receives the greatest possible power, although the efficiency is only 50%.
