Power

Rate of doing work with respect to time is called power.

Mathematical formula of power

Power = work / time

Unit of power

The si unit of power is watt

It is a scalar quantity.

Definition of watt

If a body does a work of one joule in one second then its power will be one watt (W).

The bigger units of power: 1 KW = 1,000 W

1 MW = 1,000 KW = 1,000,000 W

## Related Questions Power = energy / time. Energy = power x time.Power = energy / time. Energy = power x time.Power = energy / time. Energy = power x time.Power = energy / time. Energy = power x time. Well, you might just put it in a separate category, and call it "light energy". But it is probably better to place it in the broader category of "electromagnetic waves". Translational energy is the energy of bodies in motion. It is a sub-category of kinetic energy, which you may be more familiar with. Power(watt) is the rate of change of energy. Take energy(joules) divide by time(seconds). u'll get power ________________________________________ Energy is the capacity to produce power Since power is defined as energy/time, if you solve for energy, you get:energy = power x timeIf the time is in seconds and the power in watts, the energy is in joules. The Saffir-Simpson Scale is an estimate of the power of hurricanes. Their Categories are Category 1, Category 2, Category 3, Category 4, and Category 5. All of them are destructive, especially Category 3 through 5. Those signals which have finite energy and zero power known as energy signal..Those signals which have infinite energy and finite power known as power signal.. Short wavelengths has more energy. (X-rays Gamma rays belongs to this category.) Long wavelengths has less energy (radio waves and light belongs to this category). I hope this would be enough.
