Question

A radio set of 0.06kw runs for 50 hrs how many units kwh of electrical energy are consumed​

Answer 1

we know that,
0.06kw=60W
1 W= 1J/s
So, 60W=60J/s
the radio runs for 50 hours so
energy expended=60J/s ×3600s×50=10800000 J
to get it in terms of units we have to divide by 3.6×10^6.
we get energy expended =3 units.
