Energy= power×time P =120 W =120 J/s Time t = 20 min = 20×60 second= 1200 second E = 120× 120 = 144000joul E =144×1000 joul =144 kilo joul

Total energy is the product of power and time... But we have to convert both to the same unit. 20 min= 20*60sec= 1200 sec.. Energy= 1200*120 J =144000 J

120 W is 120 Joules per second, and 20Minutes is 1200 seconds. Hence the total energy consumed is 1200seconds*120W = 144000 Joules or 144 Kilo Joules.

Given: Power=120W Time=t=20min=20X60Sec =1200Sec Power P = Work W ( or Energy E)/ Time taken t Then, Energy E= Power P × Time t So, Energy E= 120 W× 1200sec = 144000 J = 144 KJ.
