Question

when a metal conductor connected to left gap of metre Bridge it heated the balancing point
1) shift toward right
2) shift toward left
3) remains unchanged
4) remains at zero
which one is correct ans​

Answer 1

Answer:

If a metal conductor is connected in the left gap of a meter bridge and it is heated then balancing point shifts towards right. Thus, the correct option is (1).

Answer 2

(1) When a metal conductor is connected to left gap of meter bridge it heated the balancing point shift towards right.

Explanation:

• Meter bridge works on the principle Wheatstone bridge.
• The unknown resistance of a conductor can be found by using meter bridge.
• The point on the slide wire of the meter bridge, when the deflection of the galvanometer is zero is called balancing point.
• The metals that conducts electricity is called metal conductor. It conducts to a greater extent.
• Some examples of metal conductor are silver, copper, steel etc.
• The resistance increases when the resistor is heated, therefore, the balancing point will shift towards right in a meter bridge.
• Therefore, option 1 is correct.
