# 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…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.

# What is the difference between a watt and sunlight?

Welll, it's actually a lot like the difference between amile-per-hour and cars, or between an inch and people. -- "Watt" is a unit of measure that describes the rate at wh…ich energy is used, or produced, or moved from one place to another. -- "Sunlight" is a small portion of the stupendous amount of energythat the sun produces and pours out in every direction at a humongous rate.

# 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 …volt is a measure of electrical potential difference, and is the SI (derived) unit of electromotive force, or EMF (E). Voltage, which is measured in volts (V), is the force that drives electron current flow (I), which is measured in amps (A)..
In relationship to the volt, the watt is current flow times voltage, or, said another way, a watt is amps times volts. As regards watts and volts, they are "linked" by current. Let's look at the expressions:.
Power = Current x Electromotive force => P = I x E.
Power (in watts) = Current (in amps) x Electromotive force (in volts).
Voltage is a measure of electric potential, in joules per coulomb. Watts is a measure of energy transfer rate, in joules per second. To complete the answer, amperes is a measure of charge transfer rate, in coulombs per second, which is why voltage (joules per coulomb) time amperes (coulombs per second) is watts (joules per second).

# What is the difference between amps and watts?

Amps is an electric current unit and watt is an electric power unit.

# What is the difference between watt and KVA?

kva is an apperent power which is ac,depends on phaseangle eg-e=25cos wt.while watt is a true power which is dc eg-p=vi

# 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…s such as computers and other electronics will consume reactive power, which is measured by the VA rating. The Watt rating measures only real power. In residential settings, you will not be billed for reactive power, and so you do not need to worry about the VA rating. However, the VA rating is the "true" power required by the device, so if you are planning to hook it up to a generator or UPS, you will need to be able to provide at least that much power.

# Difference between Watts and Amps?

Watts are the units for Power while Amps or Amperes are the units for Current.

# What is the differents between volts and watts?

" volt " = unit of 'potential difference' or 'electromotive force', the 'pressure' between two points that makes electrons want to flow from one point to the other. Useful… only in connection with electrical stuff. " watt " = unit of power, the rate at which energy flows. Useful any place where energy, in any form, is being transferred, converted, or consumed.

# What is the difference between VA and watt rating of electrical appliances?

VA is meant as Apparent Power. Formula = V X A [ Voltage X Current]..
Watt is a unit of True power Formula = V X A X CosĂŽÂ¸ [ Voltage X Current X Power factor]..

# What is the difference between Hz and watts?

' Hz ' is the symbol for ' hertz ', the SI unit for frequency -equivalent to a 'cycle per second'. The frequency of your supply is 50 Hz in Europe, or 60 Hz in North America…. The ' watt ' is the SI unit for power , which is the rate at which your electrical appliances use energy.

# What was the difference between watt and horsepower?

# 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…ctor, which is 1 forsome appliances but less than 1 for others. volt-amps, or current, is only one variable of any circuit; wattagewould be the product of current times voltage, a.k.a. power Answer In purely-resistive AC circuits, the load current and supplyvoltage are said to be in phase with each other, and the product ofthese two quantities is called the true power of the load,expressed in watts . If the AC circuit is not purely resistive, then it isdescribed as being reactive , and the load current eitherlags or leads the supply voltage. In this case, the product ofthese two quantities results, not in the true power of theload, but in the apparent power of the load. Todifferentiate between apparent power and true power, apparent poweris measured in volt amperes ( V . A ) while truepower is measured in watts (W). The cosine of the angle by which the load current leads or lags thesupply voltage in reactive loads is called power factor , andhas to be taken into account when calculating the true power of thecircuit -so, in this case, true power is the product of supplyvoltage, load current, and power factor. To summarise, volt amperes are used to measure the apparent powerof a reactive load, while watts are used to measure its true power.
