Direction: Statement for Q. 10 to Q. 15.
In the circuit shown below, the voltages, currents and powers of some elements have been measured.
-
If element A generates 20W of power, find VA—
-
- 40V
- 5V
- 10V
- None of these
- 40V
Correct Option: B
The given circuit 
The element A generates 20W of power
P = VI
20 = V × 4
or
V = 5V
