Direction: Figure given below shows four light bulbs connected across an 85V battery. The bulbs are said to be connected in parallel.
-
The total power consumed in the circuit shown in the figure is—
-
- 10 W
- 12 W
- 16 W
- 20 W
Correct Option: B
The given circuit
Case 1: When current source is taken
IAB = 2A & IBC = OA (Due to S.C. of voltage source)
Case 2: When voltage source is taken
IBC = | = 1 A | 2 |
IBA = OA

So, the power consumed in the circuit
P = I2AB × 2Ω + = I2BC × 2Ω
= 22 × 2 + 12 × 2 = 10W
