Question

Power of lamp is 60W. Find the energy in joules consumed by it in 1s

Answer 1

energy=power/time
= 60/1
= 60 joules per second.....

Answer 2

Answer:

Given ,            P = 60W

                       t = 1s

Energy,           E = (VI)t

                       E = P × t = 60 × 1 J

                       E = 60 J
