Question

power ofa lamp is 60 w. . find energy in joules in 1s​

Answer 1

Energy is calculated as follows:

   

                    Energy = power x time

                               = 60 j/s x 1s

                               

                               =60 joules

The energy consumed = 60 joules.

Answer 2

1W=1j/sec

power ofa lamp is 60 w

Joule in a sec. = 60
