I've been wondering and it's white bord electrical
W
Watt.
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).
W
In electronics, a capital W is the abbreviation for Watt. A Watt is a unit of electrical power. A quantity of electrical power is usually expressed as the amount of Watts consumed over a period of time. For example: kWH (kilowatt per hour)
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.
The SI unit for power, thermal or mechanical, is the watt, W. 1 W = 1 J/s (joule/second).
VA and W both are units of power. VA indicates the power is of an electrical nature. W does not distinguish whether the energy source is electrical, mechanical, magnetic, heat or otherwise.
W is short for watt, which is a unit of power. 1 watt is the same as 1 joule/second.
The unit of measurement that represents true power is the watt (W).
