W
A unit of electrical power is called a watt, symbolized by "W". It represents the rate at which electrical energy is consumed or produced by a device.
Power is simply the rate of doing work or of heat transfer. Accordingly, there is no such thing as 'electrical' or any other sort of power. Power is simply a rate, and its unit of measurement is the watt (symbol: W).
Watt.
W
Watts. Also for any other type of power (energy / time), that is, for transfer of energy that is not electrical in nature.
The symbol for the unit of measurement of power is "W" for watt.
Power is measured in the unit of watts (W) in physics.
The SI unit for power is the watt, symbolized as W.
The SI units for mechanical and electrical Power are the Watt (W), and the Watt (electrical) (We) respectively.Power is the rate of doing work, or at which energy is converted. It can be thought of as - "amount of energy used to perform work, or converted from one form to another, in a specified period of time, namely, in a second".The equation is P=W/t, where P is Power, W is the work done and t is the time taken. The equation, P=E/t, where E is the amount energy used to do the work, means the same thing. The unit for Energy is the Joule (J), and the unit for time is the second (s). The unit of power is then the watt,which is equal to 1 Joule (J) per second (s).Electrical PowerThere are a few different formulae depending on whether voltage, current or resistance are being considered. Electrical power is equal to the amount of current times the voltage, or P=IV. Electrical power is also equal to the current squared times the resistance, P=I2RThere are other formulae for the average electrical power of a sinusoidal voltage, but this is beyond the scope of this question.
