Question

an electric bulb of 60 w is used for 6 h per day calculate the units of energy consumed in 1 day by the bulb...​

Answer 1

so energy=power×time

=60×6hours(1day=6hours)

now convert hour into second

60×6×60×60=60×21,600s

=1,296,000 joule Ans ...

1,296,000÷3,60,000=0.36 unit..

hope it may help you

Answer 2

Answer:

0.36 units

Step-by-step explanation:

Power of the electric bulb = 60 W

= 0.06 kw

Time used , t = 6 h

energy = power × time taken

= 0.06 kw × 6 h

0.36 kw h

0.36 units'

the energy consumed by thecbulb is 0.36 units'.
