STANDARD Physics Potential Difference MCQ Question
Type: MCQ-conceptual-Medium-Class 12
In the given circuit the potential at point B is zero, the potential at points A and D will be
A
Vₐ = 4 V; V_d = 9 V
B
Vₐ = 3 V; V_d = 4 V
C
Vₐ = 9 V; V_d = 3 V
D
Vₐ = 4 V; V_d = 3 V
Correct Answer
Option D
Detailed Explanation
The potential difference Vₐ - V_b = 2 × 2 = 4 V. Since V_b is zero, Vₐ = 4 V. Similarly, V_d = V_c - 3 V = 3 V, where V_c is the potential at point C.
