Solution

The correct option is A ampere, hour
Energy = Work done $(i n W a t t) = P o w e r \times t i m e = V o l t a g e \times c u r r e n t \times t i m e$

$W o r k d o n e (i n k i l o w a t t) = \frac{(V o l t a g e \times c u r r e n t \times t i m e)}{1000}$

$O r w o r k d o n e (i n k i l o w a t t) = \frac{(V o l t \times a m p e r e \times h o u r)}{1000}$
