Question

If an electric bulb consumes 2400 J energy in a minute, calculate the power of the bulb?

Answer 1

Energy consumed =2400J
time=1 min=60s

Power =E/T=2400/60
=40
P=40W
 Power of the bulb =40W

Answer 2

Answer:

40 watt

Explanation:

Power:  The word Power in Physics means rate of doing a work, i.e how much energy it consumes in the given time.

Now what is energy?

Energy in physics means capacity of doing a work. It may exist in potential, kinetic, thermal, electrical, chemical, nuclear, or other various forms

So now according to the given question:

Energy=2400 J

Time = 1 minute = 60 seconds

So we know from the definition of Power = Energy/Time

p=E/t

p=(2400/60) joules/ seconds

p=40 W
