A resistance \(R\) is to be measured using a meter bridge. A student chooses the standard resistance \(S\) to be \(100~\Omega .\) He finds the null point at \(l_1 = 2.9~\text{cm}.\) He is told to attempt to improve accuracy. Which of the following is a useful way?
| 1. | He should measure \(l_1\) more accurately |
| 2. | He should change \(S\) to \(1000~\Omega\) and repeat the experiment |
| 3. | He should change \(S\) to \(3~\Omega\) and repeat the experiment |
| 4. | He should give up hope of more accurate measurement with a meter bridge |
