List of top Electrical and Electronics Measurements Questions on Wheatstone Bridge asked in GATE IN

In the bridge circuit shown, the voltmeter \( V \) showed zero when the value of the resistors are: \( R_1 = 100 \, \Omega \), \( R_2 = 110 \, \Omega \), and \( R_3 = 90 \, \Omega \). If \( \frac{R_1}{R_2} = \frac{R_A}{R_B} \), the value of \( R_4 \) in ohm is \(\underline{\hspace{2cm}}\).
