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).

the answer for the si unit of power is the watt or w

The unit rate of power is the watt (W).

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'.

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.

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 unit of power in the SI is watt; 1 W = 1 J/s.

Power is measured in watts (W) in the SI system.

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.

MKS unit of power is "Watt 'W' (1W=1J/s)" CGS unit of power is "egr(cgs unit of work)per second"

Electrical power is measured in Watts (Unit) represented by 'W' (Symbol).To calculate it, you multiply the supply voltage by the current taken in by the device/equipment/machine you're operating.Anyway, let's say you had a heater which had a current of 16 Amps and took a single-phase supply voltage of 230V (a normal house supply):To get power, you would write the following formula:W = V x IWhich translates as:Power = Voltage x Current [SYMBOL - I and UNIT - Amps (A) ]You would then calculate:W = 230 Volts x 16 Amps = 3680 Watts [or 3.68 Kilowatts]You have now established that your heater takes in3680 Watts of electrical power.

The SI unit of power is the watt, W, a watt is joules per second.

Joules per second J/s or the Watt W

If you are defining electrical pressure as voltage then the answer to your question is yes. W = A x V.

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.

E. W. Kimbark has written: 'Electrical transmission of power and signals'

No. Electrical power is measured in watts, abbreviated to the upper-case W. Coulomb is a measure of electric charge.

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 that 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).Therefore, you should see that the Watt is equal to 1 Joule (J) per second (s).There is also electrical power which should be considered, and there 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=IVAlso, electrical power is 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 outwith the scope of this answer.

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.

This depends on the situation. The main power unit used for electric power output is generally the Watt (W), while the main power unit used for mechanical power output is often the horsepower (hp).

The SI unit of power is the watt (W), which is equal to one joule per second.

Unit of Electric PowerNormally in KWh (Kilowatt - hour). CommentThe kilowatt hour (kW.h) is a measure of energy, notpower. Power is measured in watts (W).
