Sagot :
Answer:
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.
The formula is given by
[tex]\\ \rm\Rrightarrow R=\rho\dfrac{\ell}{A}[/tex]
- 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
