Question

A cell of emf ‘E’ and internal resistance ‘r’ draws a current ‘I’. Write the relation between terminal voltage ‘V’ in terms of E, I and r. ​

Answer 1

Answer:

When a current I draws from a cell of emf E and internal resistance r, then the terminal voltage is V=E-Ir.

Answer 2

Answer:

whenever a cell a draws a current of I with an internal resistance of r the value of (v) becomes v= E - Ir
