Question

Calculate the value of the resistance R in the circuit shown in the figure so that the current in the circuit is 0.2 A. What would b the potential difference between points A and B?

Solution

Apply Kirchhoff’s loop law in loop UVWXU:-

5(0.2) + R (0.2) + 10(0.2) = 6 − 2

⇒ R = 5Ω

VAB = VVW 5(0.2) = 1V
