MCQ
How much energy does a 100W electric bulb transfer in 1 minute?
  • A
    100J
  • B
    600J
  • C
    3600J
  • D
    6000J
✓

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.
