Find the internal resistance of the battery E1.

For the arrangement of the potentimeter shown in the figure, The balance point is obtained at a distance 75cm from A when the key k is open The second balance point is obtained at 60 cm from A when the key k is closed. Find the internal resistance of the battery E1.

For the arrangement of the potentimeter shown in the figure The maximum current in a galvanometer can be 10 mA. Its resistance is 10 Ω. To convert it into an ammeter of 1 A what resistance should be connected in parallel with galvanometer (in 10/ohm)?
