Wheatstone Bridge Hard

Question

Balanced Wheatstone bridge condition:

RankGuru · Accepted Answer

A Wheatstone bridge is in balance when no current flows through the galvanometer in the bridge arm ($I_g = 0$).
- This occurs when the potential at the two junction points of the galvanometer arm is equal.
- For a bridge with resistors $R_1, R_2$ on one side and $R_3, R_4$ on the other side of the junctions:
$\frac{R_1}{R_2} = \frac{R_3}{R_4}$
