Question

An electric bulb of 50W is used for 6 hours per day. Calculate the 'units' of energy consumed in one day by bulb

a)0.3 units
b)0.3 kwh
c)0.26 units
d)both a and b

Answer 1

Power = 50 W = 0.05 kW
Time = 6h

Energy used = Pt = 0.05×6 = 0.3 kWh = 0.3 unit

So the answer is d)both a and b

(Note: 1 kWh = 1 unit)
