In a given meter bridge, the current flowing through $40 \Omega$ resistor is

A
$\mathrm{I}_2+\mathrm{I}_{\mathrm{g}}$
B
$\mathrm{I}_{\mathrm{g}}$
C
$\mathrm{I}_2-\mathrm{I}_{\mathrm{g}}$
Correct answer
D
$\mathrm{I}_2$

Solution

As the bridge is balanced, no current will flow through the galvanometer. Hence, the current through the $40 \Omega$ resistor will be $I_2$.

Hence, the correct answer is option: 'D'.
