AIPMT MAIN 2008 Physics Power in Electric Circuits MCQ Question
Type: MCQ-numerical-Medium-Class 12
A current of 3 amp. flows through the 2 Ω resistor shown in the circuit. The power dissipated in the 5 Ω resistor is
A
5 watt
B
4 watt
C
2 watt
D
1 watt
Correct Answer
Option A
Detailed Explanation
The potential difference across the 2 Ω resistor is 6V. The current through the 5 Ω resistor is 1A. Therefore, the power dissipated in the 5 Ω resistor is (1)² × 5 = 5 Watt.
