Question

relation between watt hour and joule.

Answer 1

1 kilo watt hour =
$3.6 \times {10}^{8}$
Joule

Answer 2

Capacity of Work = Energy .

Power = energy / time

= > 1 W = 1 J / 1 s

= > 1 W s = 1 J .

1 s = 60 min

    = 60 × 60 hr

    = 3600 hr

1 W s = 1 J

= > 1 J = 3600 W hr

This is the relation .
