Direction: Statement for Q. 10 to Q. 15.
In the circuit shown below, the voltages, currents and powers of some elements have been measured.
-
Find ID if element D absorbs 27W of power—
-
- – 9A
- 9A
- 4A
- – 4A
- – 9A
Correct Option: A
The absorbed power will be positive if current exit from the positive terminal
Since here current enters at negative terminal, it means element D is delivering power.
PD = – IDVD
or
| ID = – | = | = -9A | ||
| VD | 3V |
