Question

In an experiment of meter bridge, a null point is obtained at the centre of the bridge wire. When a resistance of 10 ohm is connected in one gap, the value of resistance in other gap is (A) 10 Ω (B) 5 Ω (C) (1/5) Ω (D) 500 Ω

Meter bridge is balanced, therefore (P/Q)=(R/S) text or 1=(10/S) ⇒ S=10 ohm

Q. In an experiment of meter bridge, a null point is obtained at the centre of the bridge wire. When a resistance of $10 o hm$ is connected in one gap, the value of resistance in other gap is

$10 Ω$

$5 Ω$

$\frac{1}{5} Ω$

$500 Ω$

Meter bridge is balanced, therefore
$\frac{P}{Q} = \frac{R}{S} or 1 = \frac{10}{S} \Rightarrow S = 10 o hm$
