When the load resistance equals the generator resistance which of the following will be maximum __________?
Correct answer: C. Power in the load resistance
- A. Current
- B. Efficiency of the circuit
- C. Power in the load resistance
- D. Voltage across the load resistance
Explanation
For a source with internal resistance, maximum power transfer occurs when the load resistance equals that internal resistance. At this point the load power is maximum, although efficiency is only 50%, not maximum.
