Question

Mention two factors on which the internal resistance of a cell depends.​

Answer 1

Step-by-step explanation:

(1) The surface area of the electrodes: Larger the surface area of the electrodes, less is the internal resistance.

(2) The distance between the electrodes: As the distance between the electrodes increases, the internal resistance of cell also increases.

Answer 2

The formula is given by

`\\ \rm\Rrightarrow R=\rho(\ell)/(A)`

• rho is resistivity
• l is length of cell
• A is surface area.

On these three factors resistance depends

also

According to ohms law

• V/I=R

Resistance also depends on voltage and current
