Question

Each of the resistors shown in figure (32-E11) has a resistance of 10 $\Omega$ and each of the batteries has an emf of 10 V. Find the currents through the resistors a and b in the two circuits.

Answer 1

(a) Potential difference between terminal of a is 10 V.

i through a = 1 A

Potential difference between terminal of b is 10 - 10 = 0 V

i through b = 0 A

(b) Potential diff. across a is 10 V.

i through a = 1 A

Potential diff. across b is 10 - 10 = 0 V

i through b = 0 A
