Answer:
The electricity consumed by the bulb per day is 250 watt-hour. Here, P is the power, E is the energy and t is time. Given P = 25 W, t = 10 hour. Thus, the electricity consumed by the bulb per day is 250 watt-hour.

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.
