What is the formula for calculating energy?

The formula that links energy and power is: Energy = Power x Time. The unit of energy is the joule, the unit of power is the watt, and the unit of time is the second.

How many joules are in a Watt?

1 Watt-hour is equal to 3600 Joules (3.6kJ). One Kilowatt-Hour is the same as 1,000 Watt-hours and is the most common unit used in electrical energy consumption.

What is the formula of work?

The work is calculated by multiplying the force by the amount of movement of an object (W = F * d). A force of 10 newtons, that moves an object 3 meters, does 30 n-m of work. A newton-meter is the same thing as a joule, so the units for work are the same as those for energy – joules.

Which is the largest unit of energy?

Since, we know that SI unit of energy is represented by Joule. Hence, let us convert all the different units in the form of Joules. Hence, Option B is the largest unit of energy and hence it is practically used in everyday life of electric consumption.
