Question : 10 of 76

Marks: +1, -0

Choose the correct relation for e.m.f. (

ε

) and terminal voltage

V

Solution:

(c)

{\V}< ε

[when the cell is in use]
Explanation : When the current is drawn from the cell, terminal voltage

(V)

is less than the emf

(ε)

of the cell due to potential drop (or voltage drop) across the internal resistance of the cell.
