12.The resistance of the series combination of two resistances is S. When they are joined in parallel, the total resistance is P. If S = nP, then the minimum possible value of n is: |
| 4 |
| 3 |
| 2 |
| 1 |
13.The sensitivity of a potentiometer can be increased by: |
| decreasing the length of potentiometer wire |
| increasing the length of potentiometer wire |
| increasing the emf of the cell used in primary circuit |
| all the above methods |
14.For accurate measurements, the resistance of a voltmeter should be: |
| as large as possible |
| equal to the resistance across which the potential difference is to be measured |
| as small as possible |
| infinity |
15.A big dry cell A and a small dry cell B have the same emf. The internal resistance of A: |
