Question

BRAINLIEST AND MAY DOUBLE POINTS!!!

how much power would a light bulb have if it used 30 joules of energy every 3 seconds

Answer 1

Given that:

 Energy of bulb  (Work ) = 30 J,

 Time (t) = 3 sec

The power consumption =  ?

 We know that, Power can be defined as rate of doing work

              Power (P) = Work(Energy supplied) ÷ time

                               = 30 ÷ 3

                              = 10 Watts

The power consumption is 10 W.
