Question

a lamp consumes 1000 joule of electrical energy in 10 seconds what is its power

Answer 1

Power=work done/time

Work done=energy consumed by the lamp=1000J
Time=10s

Power=1000/10=100J s^-1
=100W

Hope this helps you!! :)

Answer 2

Answer:

Power of the lamp is 100 watt

Explanation:

here, the energy consumes by the lamp is 1000 joule

so, work done = 1000 joule

    time = 10 sec

we know, power = work done / time

               power = 1000/ 10

               power = 100 watt

therefore, power of the lamp is 100 watt.
