Joules versus watts The joule and the watt are closely related units. The joule is a unit of work and energy. It is equal to a newton-meter (N-m). Note that the unit of …torque is also the newton-meter, but scientists don't use the word joule when they are talking about torque. The watt is a unit of power and is defined as a joule per second , so you can see that power is work per unit time. One joule is equal to one watt-second.
VA or volt-amps is also volts times amps, the concept however has been extended to AC power. For DC current: VA = Watts (DC current). . In AC if the volts and amps are in p…hase (for example at a resistive load) then the equation is also: VA=Watts (resistive load) where V is the RMS voltage and A is the RMS amperage.
Answer . The volt is a measure of electric potential difference or electromotive force.. The watt is a unit of power which measures a rate of energy use.. Scroll down to re…lated links and look at "Electrical voltage V , amperage I , resistivity R , impedance Z , wattage P ".
Amps is an electric current unit and watt is an electric power unit.
Both are used to measure power . The horsepower is simply the Imperial unit for power, whereas the watt is the SI unit for power, where one horsepower is equivalent to 74…6 watts. In North America, it is traditional to measure the output power of an electric motor in horsepower, while the watt is used to measure its input power . Elsewhere in the world, the watt is used to measure both input power and output power. (The difference between output power and the input power is due to losses, such as heat transfer, friction, windage [air resistance], etc.) Outside North America, the output power of a car engine is now measured in kilowatts rather than in horsepower.
A volt is one individual unit of measurement, used in the formula to calculate the watt, which is overall power The equation is simple: W = V*A W = Power In watts A = Ampe…res (Amps) V = Voltage (Volts)
Watts is the product of amps times volts. W = A X V. Electricially put W=IxE where w= watts, I= amps, E= volts. watts = unit of power . amps or ampere = unit of electric cur…rent . volts = unit of voltage supplied See also: http://www.wisegeek.com/what-is-the-difference-between-an-amp-volt-and-watt.htm
Amps are units of current, watts are units of power. Watts are the product of Amps times Volts. Watts = Amps x Volts.
None. The ampere is the unit for electric current, while the watt is the unit for power. They are two different quantities, so their units of measurement are unrelated.
Amps are just a general measurement of electric current in any application, whereas the term cranking amps are specific to automotive / starting battery applications. Cranking… amps is a measure of the maximum current a car/ starting battery can produce in normal temperatures for 30 seconds before the battery voltage drops too much.
A watt is a rate (speed) of using energy ... 1 joule per second.
The relationship is, a watt is the product of amps x volts.
Volt-Amp is apparent power, in direct current Volt x Amps = power with unit of Watt. For Alternate Current Volt-Amp is generally different from real power because the power su…pply in wave form and might be out of phase and portion of energy is not usable. Volt-Amp is always higher or equal to real power in AC.
Amps is a measure of current flowing in a circuit. Volt-Amps or (VA) is a measure of power and is equivalent to wattage for a pure resistive load.
The watt is used to measure the true power of an a.c.load. It is the product of the supply voltage, the loadcurrent , and the power-factor of the load. The volt ampe…re is used to measure the apparent power of an a.c. load, which is the product of the supply voltage and the load current .
Volts is the unit of Voltage, denoted by 'V'. Watts is the unit of power consumed, denoted by 'W'. As per Indian Standards we are available with 230V single phase connect…ions. And the incandescent bulbs calibrated with some 40W, 60W, 100W shows how much power will it consume for an hour of consumption. Means a 40W bulb will draw 40W power on lighting it for an hour. Hope now its all clear with Volt and Watts difference.
