Problem

Consider a Wheatstone bridge where the resistances in the arms are

R_{1} = 100\,\Omega

R_{2} = 10\,\Omega

R_{3} = 60\,\Omega

, and

R_{4} = 5\,\Omega

(in cyclic order). A galvanometer of resistance

G = 15\,\Omega

is connected between the opposite junctions

B

and

D

. A battery of

10\,\text{V}

is connected across

A

and

C

. Calculate the current flowing through the galvanometer.
