Question
How much energy does a 100W electric bulb transfer in 1 minute?
✓

Answer

  1. 6000J
Explanation:
Power, (P) = 100W
Time duration, (t) = 60s
Now, we can calculate the electrical energy consumed as,
Energy consumed = (Power)(Time)
So,
Energy consumed
 = (100)(60)J
= 6000J
So, the energy consumed is 6000 J.
