1. In a Wheatstone’s bridge, three resistances

$P$ ,

$Q$ and

$R$ connected in the three arms and the fourth arm is formed by parallel combination of

$S_1$ and

$S_2$ then condition for the bridge to be balanced will be:

2. In an experiment to measure the internal resistance of a cell by a potentiometer, it is found that the balance point is at a length of

$2\ m$ , when the cell is shunted by a

$5\ \Omega$ resistance and at a length of

$3\ m$ , when the cell is shunted by a

$10\ \Omega$ resistance. The internal resistance of the cell is then
