When a metal conductor is connected to left gap of meter bridge is heated, the balancing point
A
remains unchanged
B
Shifts towards right
C
Shift to the center
D
Shifts towards left
Answer
Shifts towards right
Explanation
Solution
When a metal conductor connected to the left gap of a meter bridge is heated, the balancing point will shift towards the right. This is because heating the conductor increases its resistance. As a result, the resistance in the left gap of the meter bridge increases, causing the balancing point to shift towards the side with lower resistance, which is the right side.
