We know that Power = Voltage(V) X Current(I) and power is measured in terms of watts as well as volt-amperes. However, for AC circuits, based on the observation that the voltage considered is often an average measure, VA often tends to be a far higher number as compared to the actual "wattage".

Based on some information I found at the Argonne national laboratory site:
the explanation found was:

1 joule = the energy generated when 1 ampere of electrical
current, passes through an electrical potential drop of 1 volt. Energy =
Volts x Current.

1 watt = 1 joule/second.

So joules is a quantity of energy, and watts is the RATE of generation of
energy. Watt = Energy / second.

What are the differences between a joule and a watt?

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

What is difference between watts and VA?

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

Difference between rms and watts?

RMS means root mean square and watts means power. What a difference!. Scroll down to related links and look for a neat pressure converter at "Root Mean Square" und knowlege

What is the difference between a watt and a volt?

A watt is a measure of power , and a volt is a measure of electrical potential difference . A watt is a volt times an amp. Said another way, power (P, given in watts) is

What is the difference between watts and volts?

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

What is the difference between volts and watts?

Watts is the product of amps and volts. It's amps times volts.. The watt (W) is a measure of power (P). It's the SI unit of power, actually, and it's a joule per second. The

What is the difference between a watt and horsepower?

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

What is the difference between watt and volt?

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

What is the difference between va and watt rating of an electrical appliance?

\nDepends on the appliance, and in most cases, it does not matter. For a purely resistive appliance, such as a kettle, or a toaster, the two should be the same. Certain device

What is the difference between V-A and Watt?

In a DC circuit, the power in watts is the volts times the amps. Inan AC circuit, the volts times the amps is called the VA, and thepower in watts is the VA times the power fa

What is the difference between WATTS and VA?

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

What the difference between watts and volts?

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
