Question

A cell is joined in series with a resistance of 2ohms
and a current of 0.25 A flows through it. When a
second resistance of 2ohms is connected in parallel
with the first, the current through the cell
increases to 0.3 A. Calculate:
(a) the EMF and
(Ans. 1.5 V
(b) the internal resistance of the cell. [Ans. 4ohms)
