A resistance R is to be measured usnig a meter bridge, student shooses the standard resistance S to be `100Omega`. He finds the null point at `I_(1)=2.9cm`. He is told to attempt of improve the accuracy. Which of the following is a useful way?

A

He should measure `l_(1)` more accurately.

B

He should change S to `1000 Omega` and repeat the experiment.

C

He should chandge S to `3 Omega` and repeat the experiment.

D

He should give up hope of a more accurate measurement with a meter bridge.
