Question

a 25 W electric bulb is used for 10hours everyday. how much electricity does it consumes each day. ​

Answer 1

Answer:

Given :

P= 25, W=0.025kW

energy consumed =power *time

= 0.02025*10

energy =0.25kW hr

Answer 2

Answer:

The electric bulb consumes 0.25 k W hr energy each day.

Explanation:

P = 25 W

So,

1000 W = 1 k W

=> P = 25 W

=> P = 25/1000 kW

=> P = 0.025 k W

Energy consumed = Power * Time

=> E = 0.025 * 10

=> Energy = 0.25 k W hr

The electric bulb consumes 0.25 k W hr energy each day.
