<u>Answer</u>:

The energy that is consumed by the computer in 10 seconds that uses a power of 200 watt is 5.55 * 10^{-4} \mathrm{KWH}

Explanation:

Given:

Power used by the computer=200W

Time used by the compute=10seconds

To Find:

The Energy Consumed by the computer=?

Solution:

1 W a t t=\frac{1}{1000} W a t t

1Watt=1/1000 Watt

so,

200 Wa t t=\frac{200}{1000} Wa t t

1 \text { second }=\frac{1}{3600} \text { seconds }

So,

10 \text { seconds }=\frac{10}{3600} \text { hours }

Now substituting the values we get ,

Energy = Power * Time

\text { Energy }=\left(\frac{200}{1000}\right) *\left(\frac{10}{3600}\right)

\text {Energy}=(0.2) *(0.00277)

\text {Energy}=5.55 * 10^{-4} \mathrm{KW} \mathrm{H}

Hence the energy consumed is =5.55 * 10^{-4} \mathrm{KW} \mathrm{H}

Answer:

<u>The correct answer is 0.556 Watts</u>

Explanation:

The computer monitor uses 200 Watts of power in an hour, that is the standard measure.

If we want to know, how much energy the computer monitor uses in one second, we will have to divide both sides of the equation into 3,600.

1 hour = 60 minutes = 3,600 seconds (60 x 60)

Energy per second = 200/3600

Energy per second = 0.0556 Watts

Therefore to calculate how much energy is used in 10 seconds, we do this:

Energy per second x 10

<u>0.0556 x 10 = 0.556 Watts</u>

<u>The computer monitor uses 0.556 Watts in 10 seconds</u>
