Question

If an electric iron of 1600w is used for 45min. Every day find the electric energy consumed in the month of march

Answer 1

power of electric iron =1600w=1.6kw

time=45min=0.75hr

energy=power*time taken

=1.6*0.75

=1.2kwhr

It is used for month of march

march has 31 days

therefore, the energy used for 31 days=1.2*31

=37.2kwhr
