A source V=36 V with internal resistance Rs=6, supplies a variable load RL, as shown. For what value of RL is the power delivered to the load a maximum?
- 12,
- 3,
- 4.5,
- 6,
Answer
D. 6,
Solution
Maximum power transfer occurs when the load resistance equals the source (Thevenin) resistance: RL=Rs=6, .
