Question

A 60-W light bulb runs on 120 V and draws 0.50 A of current when running

Answer 1

Answer:

3600 J

Explanation:

According to given question

P(rated)=60w

V= 120

I =0.50 A

t=600 second

Now,

Energy can be calculated as :

$E= VI*t$

Where,

V is voltage

I is current

t is time in second

Now,

Putting the all value in above equation E

So,

$E=120*0.5*600\\E=36000 J$

Therefore, 36000 J energy use up by light bulb
