Question

In the balanced condition, the values of the resistances of the four arms of a Wheatstone bridge are shown in the figure below. The resistance $R_{3}$ has temperature coefficient $00004^{\circ} C ^{-1}$. If the temperature of $R_{3}$ is increased by $100{ }^{\circ} C$, the voltage developed between $S$ and $T$ will be ______ volt

Answer 1

Correct Answer: 0.27

Voltage developed between S and T will be 0.27 V.
