Question

An electric bulb of 60w is used for 8hours per day. Calculate the units of energy consumed in 30 days by the bulb.

Answer 1

1 unit of energy is =1 kw/h

P=60w=60/1000=0.06kw(1kw=1000w)

Time =8 hours

Energy consumed=P T=0.06 X 8 KWH=0.48KWH

ENERGY CONSUMED IN 30 DAY

=30 X ENERGY=30 X 0.48=14.4kwh

So enery consumed in 30 days is 14.4kwh
