Question

if an eletric iron of 1200 w is used for 30 min everday find electric energy consumed in the month of april

Answer 1

GIVEN:
power=1200W=1.2KW
time=30min=1/2hr

energy consumption in one day =P×t
E=1.2×1/2=0.6KWh

energy consumption in the month of April :
=30×0.6=18KWh

Answer 2

We have Given:
Power of electric iron=1200W
Usage per day =30min=30/60hrs=0.5hrs
Number of days in the month of April=30days
Electrical energy consumed,
E=Pxt
1200x0.5x30=18000WH=18KWH=18units

Hence, The Total Electricity consumed in the month of april is 18 units
