Value of the resistance R, connected across the terminals A and B, (see given figure), which will absorb maximum power, is __________ kΩ
-
- 4.00
- 8
- 64
- None of the above
Correct Option: A
The circuit is drawn below by shorting the voltage source.
Taking Thevenin's equivalent between points A, B, we have
| RTh = |  | + |  | kΩ = 4 kΩ | ||
| 6 + 3 | 4 + 4 |
For maximum power transfer, R = RTh = 4kΩ
