In a meter bridge experiment, with a standard resistance in the right gap and a resistance coil dipped in water (in a beaker) in the left gap, the balancing length obtained is $l$ . If the temperature of the water is increased, the new balancing length

Options:

Answer:

Solution:

According to the question,

$\frac{R_{u n k n o w n}}{R_{s t a n d a r d}} = \frac{l}{(1 - l)}$

If temperature increases than resistance increases. Hence the new balancing is greater than $l$
