Q. A 5.0 A current is setup in an external circuit by a 6.0 storage battery for 6.0 min. The chemical energy of the battery is reduced by
A) $1.08 \times 10^{4}\ J$
B) $1.08 \times 10^{3}\ J$
C) $1.8 \times 10^{4}\ J$
D) $1.8 \times 10^{3}\ J$
Explanation
(a) Chemical energy reduced
$= VIt$
$= 6 \times 5 \times 6 \times 60 = 10800$
$= 1.08 \times 10^{4}\ J$
