Electrical power is measured in watts. The formulas for power dissipated by a resistor are:
* P = V × I * P = V² / R
* P = I² × R P is power, V is voltage, I is current, R is resistance.
power=work/time (P=E/t) [1W=1J/1s]
power=force*distance/time (P=F*l/t) [1W=1N*1m/1s]
power=current*voltage (P=I*V) [1W=1A*1V]
Power unit is Watt (W)
Energy units
1 watt second = 1 joule
The power in a resistor (in watts) is simply the product of the current (in amperes) times the voltage (in volts).The power in a resistor (in watts) is simply the product of the current (in amperes) times the voltage (in volts).The power in a resistor (in watts) is simply the product of the current (in amperes) times the voltage (in volts).The power in a resistor (in watts) is simply the product of the current (in amperes) times the voltage (in volts).
The formula for watts (or power) is Amps times voltage. Therefore with a 6 amp draw times 120 volts would be about 720 watts. A 1000 watt power inverter would do the job.
The formula that you are expressing is Watts = Amps x Volts. There are two other ways to express watts. W = E (squared)/R and W = Amps (squared)/R. R is the resistance of a device in ohms.
The formula you are looking for is Watts = Amps x Volts. killo = 1000 1 kw = 1000 watts.

The watt is a measurement of power. In electrical circuit, to determined watts there is a formula volts x amps = watts
power in watts = voltage in volts x current in amps. or power in watts = current in amps x (resistance in ohms) squared i think what you meant was power in watts =(current in amps)squared x resistance in ohms
Power is calculated by the following formula, Watts = Amps x Volts.
8,000 watts = 8 kVA / (the power factor) If the power factor is 1, then 8 kVa = 8,000 watts.
Power = Voltage x Current Watts = volts x Amps
A watt is a unit of power, and power is given by P = IV where P is power, I is current and V is voltage. Therefore, P = (15A)*(120V) = 1800V*A = 1800W
To find the power in watts, multiply the current (5.0 amps) by the voltage (which is needed to provide the full power calculation). Without voltage information, we can't determine the power in watts solely from current (amps).
Watts and Amps are two separate things. Watts is a measure of Power and Amp (Ampere) is a measure of electrical current. Look at the following formulae. Formula 1: W=V x I where W is Watts, V is Volts and I is Amps. Formula 2: I=V/R where I is Amps, V is Volts and R is Resistance (in Ohms) Formula 2 can be written as V=IxR and if you put this into Formula 1 you get a third formula which is: Formula 3: W=IxIxR So Power W is proportional to Current I squared. Note that milliAmps are Amps/1000 Ray Ashmore, Helston
AC power is electricially, a value that is expressed in watts and voltage is the electromotive force that combined with amps, makes up the formula to find watts. Watts is the product of Amps x Volts. W = amps x volts.
The power (in watts) can be calculated using the formula: Power (W) = Voltage (V) * Current (A). In this case, the power required to run the 3 amp well pump on 220 volts is 660 watts (220 V * 3 A = 660 W).
volts times amps equal watts, or 550 lbs per sec equals 1 horse power.
Use the formula: P=IR (power = current x resistance).
