Question

When a metal conductor connected to left gap of a meter bridge is heated, the balancing point (A) Remains unchanged (B) Shifts to the center (C) Shifts towards right (D) Shifts towards left

Tardigrade Admin · Accepted Answer

( R /ℓ)=( S /100-ℓ) If temperature increases, resistance increases. As R increases, balancing length also increases. It will shift towards Right

Q. When a metal conductor connected to left gap of a meter bridge is heated, the balancing point

Remains unchanged

Shifts to the center

Shifts towards right

Shifts towards left

$\frac{R}{ℓ} = \frac{S}{100 - ℓ}$
If temperature increases, resistance increases.
As $R$ increases, balancing length also increases. It will shift towards Right
