For high efficiency of transfer of power, internal resistance of the source should be____________?
Correct answer: B. less than the load resistance
- A. equal to the load resistance
- B. less than the load resistance
- C. more than the load resistance
- D. none of the above
Explanation
For high efficiency, the source resistance must be much smaller than the load resistance, so only a small fraction of power is lost internally. Equality of source and load resistance gives maximum load power, but only 50% efficiency.
