A current of 15 mA flows in the circuit as shown in figure. The value of potential difference between the points A and B will be

Options

  1. A50 V
  2. B75 V
  3. C150 V
  4. D275 V

Correct answer

D. 275 V

Step-by-step solution

Using current division rule, Current, i 1 = 5 10 + 5 × 15   mA = 5   mA Now, using Kirchhoff's voltage law- in lower loop, V A - 5 i - 10 i 1 - 10 i = V B Potential difference between A and B is V A - V B = 75 + 50 + 150 = 275   V
