Each of the resistors shown in figure has a resistances of `10(Omega)`and each of the batteries has an emf of 10V.Find the currents through the resistors a and b in the two circuits.

Explanation

(a) Potential difference between terminal
of a is 10 V.
i through a = 1A
Potential difference between terminal of
b is 10 - 10 = 0V.
i through b = 0 A .
(b) Potential diff. across a is 10V.
i through a = 1A
Potential diff. across b is 10- 10 = 0V.
i through b = 0A.
