I've been wondering and it's white bord electrical
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).
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 answer for the si unit of power is the watt or w
The unit rate of power is the watt (W).
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.
Both electrical and mechanical power can be expressed in units of joules/sec (joules/s) or a watt (W). In the English system feet - pounds force per second (ft-lb f/s) or horsepower (hp) can be used.
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.
W is short for watt, which is a unit of power. 1 watt is the same as 1 joule/second.
The SI unit for power, thermal or mechanical, is the watt, W. 1 W = 1 J/s (joule/second).
MKS unit of power is "Watt 'W' (1W=1J/s)" CGS unit of power is "egr(cgs unit of work)per second"
The unit of power in the SI is watt; 1 W = 1 J/s.

From The Fact Monster: (http://www.factmonster.com) watt [for James Watt], abbr. W, unit of power, or work done per unit time, equal to 1 joule per second. It is used as a measure of electrical and mechanical power. One watt is the amount of power that is delivered to a component of an electric circuit when a current of 1 ampere flows through the component and a voltage of 1 volt exists across it. The derivative units are kilowatt (1,000 W; kW) and megawatt (1,000,000 W; MW), used in electric power systems, and milliwatt (0.001 W; mW) and microwatt (0.000001 W; μW), used in electronics.
If you are defining electrical pressure as voltage then the answer to your question is yes. W = A x V.
The SI unit of power is the watt, W, a watt is joules per second.
Normally the power rating of an electrical appliance can be found on its 'Rating Plate' or, if there isn't one, use the following formula W = A x V, where W = watts, A = current and V = voltage.
Power is measured in watts (W) in the SI system.
Generally electrical sockets are designed to handle a max wattage and are labeled that way. A 25 w bulb will draw more power than the socket is designed for and could result in damage to the electrical appliance and fire.
The symbol for electrical power is; "P", and is measured in Watts (W).CommentThere is really no such thing as 'electrical' power. Power is simply a 'rate'.
