Question

for the given circuit find out the
a) total resistance of the circuit across the battery terminals.
b) potential different between A and B

Answer 1

Total resistance comes out 15 ohm

And potential diff and potential diff 2/9

Answer 2

a wheat stone bridge question so middle will get cancelled and rest when solve, will give a net resistance of 15 ohm and potential diff. between A and B is 2/15 V
