One kilowatt-hour (kwh) is the amount of work or energy generated when one kilowatt of power is supplied for a time of one hour. a kilowatt-hour is the unit of energy used by power companies when figuring your electric bill. determine the number of joules of energy in one kilowatt-hour.

The energy in one kilowatt-hour is

Explanation:

Given that,

Power = 1 kW

Time = 1 hour

One kilowatt-hour (kWh) is the amount of work or energy generated when one kilowatt of power is supplied for a time of one hour

We need to calculate the energy

Using formula of energy

Where, P = power

t = time

Put the value into the formula

Hence, The energy in one kilowatt-hour is

concave lenses are used here. they spread the light out before it reaches the convex lens in the eye, therefore letting the image focus directly on the retina. hyperopia is known to you probably as farsightedness.
