Question

In the given circuit if point C is connected to the earth and a potential of 12000 V is given to point A. The potential at B is–

• A. 1500 V
• B. 1000 V
• C. 400 V
• D. 500 V

Answer 1

Answer: (D)

500 V

Answer 2

V₁ = $\frac { 2000 \times 5 } { 20 }$ = 500

V_B – V_C = 500 ; V_B = 500 (Q V_C = 0)
