How much electrical energy is used by a 400 w toaster that is operating for 5 minutes?
LaceUp
- Please use the formula: energy = power x time
- First you must convert the time to seconds. The answer will be in joules.
- The answer is: (400 watt) x (5 x 60 seconds) = 12 0000 watt.sec = 12000 Joule = (0.4 kw) x (5/60 hour) = 0.033 Kw.h.
