Question

A 25 W electricity bulb is used for 10 hours every day how much electricity does it consumed each day​

Answer 1

Given :-

• A 25 W electricity bulb is used for 10 hours every day.

To Find :-

1. How much electricity does it consumed each day.

Formula Used :-

$\clubsuit$ Energy Formula :

$\bigstar \: \: \sf\boxed{\bold{\pink{Energy =\: Power \times Time}}}\: \: \: \bigstar$

Solution :-

First, we have to convert the power W into kW :

$\implies \sf Power =\: 25\: W$

$\implies \sf Power =\: \dfrac{25}{1000}\: kW$

$\implies \sf\bold{\purple{Power =\: 0.025\: kW}}$

Now, we have to find the energy :

Given :

• Power = 0.025 kW
• Time = 10 hours

According to the question by using the formula we get,

$\dashrightarrow \bf Energy =\: Power \times Time$

$\dashrightarrow \sf Energy =\: 0.025\: kW \times 10\: h$

$\dashrightarrow \sf\bold{\red{Energy =\: 0.25\: kW\: h}}$

$\therefore$ The electricity does it consumed each day is 0.25 kW h .
