AIPMT MAIN 2008 Physics Potential Difference MCQ Question
Type: MCQ-numerical-Medium-Class 12
In the circuit shown, the current through the 4 Ω resistor is 1 amp when the points P and M are connected to a d.c. voltage source. The potential difference between the points M and N is
A
3.2 volt
B
1.5 volt
C
1.0 volt
D
0.5 volt
Correct Answer
Option A
Detailed Explanation
The potential difference across the 4 Ω resistor is 4 V (since V = IR = 1 Å × 4 Ω). Using the potential divider rule, the potential drop between M and N is calculated as 3.2 V.
