Question

an electric bulb of 100 watt is glowing for 10 hours how much energy does it consume

Answer 1

Hii friend,

We know the formula,

Power= energy/time

Energy= power ×time

Energy=100×10

Energy=1000Wh(or)1Kwh

Hope this helps you a little!!!

Answer 2

Power = 100 w

= 0.1 Kw

Time = 10 hours

Energy consumed = Power × Time

= 0.1 × 10 kwh

= 1 Kwh
