Answer

Electrical power P=V*I

Answer

power= work / time = (force * displacement ) / Time

power = force * (displacement / time )

sooo , power = force * velocity 

Answer

Power = Work / time or  P = W / t

Answer

in electrical circut P=Voltage*Current

Answer

Ans. Power Output = Voltage * Current..cos(theta) 

 

Answer

The formula calculating work output is F*D/T, where F is the force exerted, D is the distance and T is the time.

Answer

The standard metric unit of power is the Watt. As is implied by the equation for power, a unit of power is equivalent to a unit of work divided by a unit of time. Thus, a Watt is equivalent to a Joule/second.

Answer

Electrical power is the rate at which electrical energy is converted to another form, such as motion, heat, or an electromagnetic field. The common symbol for power is the  letter P. The standard unit is the watt,symbolized by W. In utility circuits, the kilowatt (kW) is often specified instead;1 kW = 1000 W

Power = V.I       Where  V = Voltage and I = Current.

Answer

Power is product of voltage and current

P=VI

Answer

P= V.I

V IS VOLTAGE AND I IS CURRENT

Answer

Power is equal to the product of Voltage and Current in a circuit

Answer
Formula for power is P = V*I where V is voltage and I is current.
Answer

1.Power output(P)= voltage(v)*current(i)

2.Power output(P)=(voltage)^2*resistance(r)

3.Power(P)=Force(f)*velocity(v)

 the S.I. unit of power is Watt(W), larger units are KW,MW

1 HorsePower(HP)=746 kw

Answer

There are many formulae to determine power output :- 1) Power = Voltage *Current, 2) Power = (Voltage)^2/Resistance, 3) Power = (Current)^2*Resistance . The SI unit of Power is Watt (W). The larger units are kW, MW, etc.

Answer

The standard metric unit of power is the Watt. As is implied by the equation for power, a unit of power is equivalent to a unit of work divided by a unit of time. Thus, a Watt is equivalent to a Joule/second.  One horsepower is equivalent to approximately 750 Watts.
