In meter-bridge experiment, with a standard resistance in the right gap and a resistance coil in the left gap dipped in water (in a beaker), the balancing length obtained is 
. If the temperature of water is increased, the new balancing length is:
A
B
C
D
Text Solution
Verified by ExpertsThe correct answer is:
A
According to the balancing condition of the meter-bridge:
As the resistance in the left gap ( 
) increases due to the increased temperature, to maintain the balance condition, the ratio 
must also increase.
This means that the balancing length from the left end ( 
) will increase.
