In the figure below, what is the potential difference between the point A and B and between B and C respectively in steady state

Options

  1. AV_ A B =V_ B C =100 ~V
  2. BV_ A B =75 V, V_ B C =25 V
  3. CV_ A B =25 V, V_ B C =75 V
  4. DV_ A B =V_ B C =50 ~V

Correct answer

C. V_ A B =25 V, V_ B C =75 V

Step-by-step solution

The equivalent circuit is shown in figure. array l V₁+V₂=100 and 2 V₁=6 V₂ array On solving above equations, we get V₁=75 V, V₂=25 V
