Question

(C)
45. It is observed in a potentiometer
experiment that no current passes
through the galvanometer when the
terminals of cell are connected across a
certain length of potentiometer wire. On
shunting the cell by a 212 resistance, the
balancing length is reduced to half. The
internal resistance of the cell is :​

Answer 1

Answer:

It is observed in a potentiometer experiment that no current passes through the galvanometer across when the terminals of a cell are connected across a certain length of the potentiometer wire. On shuting the cell by a 2 Ω resistance, the balancing length is reduced to half.
