Question

An electric iron of 1000 W is used for 2 hr per day. Calculate the ‘units’ of energy consumed in one month by the electric iron.

Answer 1

Power of the electric iron = 1000 W
Usage per day = 2 hours
Number of days consumed = 30 days
Energy consumed = $1000W\times 2hours\times 30$
= 60000 Whr = 60 kWhr = 60 units
