The internal resistance of a cell is the resistance of

A

electrodes of the cell

B

vessel of the cell

C

electrolyte used in the cell

D

material used in the cell

Text Solution

Verified by Experts

The correct Answer is:
C
(c ) When we connect the plates of a cell bya wire, an electric current flows in the electrolyte (inside the cell) from the negative plate towards positive plate. The resistance offered by the electorlyte of the cell to the flow of current (irons) through it is called the internal resistance of the cell. Because of this resistance a part of the energy given by the cell is dissipated as heat inside the cell itself.

A potentiometer circuit with potentiometer wire 10 m long, and an ideal main battery of e.m.f 8 V, has been set up for finding the internal resistance of a given cell. When the resistance R, connected across the given cell, has values of (i) infinity, (ii) 10 omega , the balancing lengths, on the potentiometer wire are found to be 2.4 m and x respectively. If the internal resistance of the cell is 2 omega, the value of x is
