Question

if an electric iron of 1200 watt is used for 30 minutes everyday , find the electric energy consumed in the month of april ?

Answer 1

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

Answer 2

Answer:

Electric energy produced in the month of April is 18 kWh

Explanation:

Given,

P = 1200 W = 1.2 kW      

Use time per day = 30 minutes = 1 / 2 hrs

We know,

No. of days in April = 30 days

Total time iron being used

T = 1 / 2 * 30 = 15 hrs

We know,

Energy consumed = Pt

Substituting the value of P and T

= 1.2 kW * 15 hr

= 18 kWh    

Hence,

Electric energy produced in the month of April is 18 kWh
