Question

radio set of 60 Watts runs for 50 hours how many units in Kilowatt hours of electrical energy consumed

Answer 1

Commercial unit of electricity is 1 kWh.

Here, power = 60 W = 60 ÷ 1000 kW = 0.06 W, time = 50 hr

Hence, number of units = 0.06 W × 50 hr = 3 kWh or 3 units

 

Hope it is clear!

Best wishes!!

Answer 2

e=pt÷1000
=50×60÷1000
