The sliding contact $\displaystyle C$ is at one fourth of the length of the potentiometer wire ( $\displaystyle A B$ ) from $\displaystyle A$ as shown in the circuit diagram. If the resistance of the wire $\displaystyle A B$ is $\displaystyle R_0$, then the potential drop (V) across the resistor $\displaystyle R$ is
Official answer
(2)
$\displaystyle \frac{4 V_0 R}{3 R_0+16 R}$
