The definition of the ampere is : 'that constant current that, if maintained in two straight parallel conductors of infinite length and negligible cross-sectional area and placed one metre apart in a vacuum, would produce between them a force equal to 2 pi x 10^-7 newtons per unit length'.

How many watts can you get from 260 volts?

It depends on how many amperes there are. If you have 1 amperes, then you get 260 watts. If you have 260 amperes, then you have 67,600 watts. If you have 0.001 amperes, then you have 0.26 watts. Its just watts = volts times amperes. Of course, the limiting factor is the available power behind the 260 volts, but you did not say anything about that.


How many watts does a microwave use?

Find the nameplate rating it will say volts amperes watts frequency model number If watts is not on there watts= volts divided by amperes . for your estimated watts


20 amp breaker how many watts?

Watts = volts x amperes. So if your region uses 110 volts, 20 amperes is equivalent to 2200 watts; if your region uses 220 volts, 20 amperes is equivalent to 4400 watts.


How you find ups watts?

It is expressed in Volt-Amperes not Watts.


Are watts and amps the same measurement?

No they are not. Watts is a measure of the power. Amperes is a measure of the current. The equation is W = a x v ; where W is watts, a is amperes and v is volts.

What are the watts on a 1999 Ford Escort?

Volts X amperes = watts.


What power is consumed in a dc circuit of 28volts and 4 amps?

Power is voltage times amperes, so 28 volts and 4 amperes is 112 watts. The reason for this is that voltage is actually joules per coulomb, and amperes is actually coulombs per second. Multiplying them together produces joules per second, which is the definition of watts.


How do you solve watts to amperes?

Amps = Watts/Volts, or Amps = Sq Root of Watts/Resistance.


What is the relationship between watts and voltage?

Watts equals volts times amperes.


Do amperes have more power than watts?

You can't really compare that. Amperes and watts measure completely different things. On the other hand, any time there are amperes, there are also watts. The relationship is:P = I^2 x R or in units: watts = amperes squared x resistance


How do you find amperes when given volts and watts?

Use the formula: power = current x voltage. In SI units: watts = amperes x volts.


What is the relationship between amperage voltage and power?

The relationship between amperes, volts, and watts is... watts = amperes * volts Confirming by looking at the fundamental units involved... watts (joules per second) = amperes (coulombs per second) * volts (joules per coulomb)


How many watts is 8.6 amperes?

8.6 amps is zero watts without a voltage.


What is the formula to convert watts to amperes?

Amps * Watts = Volts OR, from high school algebra Amps = Volts/Watts


How many watts in 300 amperes?

There are zero watts in 300 amps. Watts are the product of amps times volts.


How many volts does 10 watts equal?

If you are talking DC voltage: 1 billion volts at 10 nano amperes is 10 watts. 1 million volts at 10 micro amperes is 10 watts. 1 thousand volts at 10 milli amperes is 10 watts. 1 volt at 10 amperes is 10 watts. So, it depends. You're comparing power to potential, which cannot be directly compared without more information (the amperage).


What is the power dissipated by a resistor that has 5 amps flowing through it with 120 volts applied?

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).


How many watts is 12 amperes?

Twelve watts is zero amps. Watts are the product of amps x volts. Without the voltage, watts can not be calculated.


Unit of electric power determined by muliplying volts times amperes?

Volts time amperes is watts. Volts is joules per coulomb. Amperes is coulombs per second. When you multiply the two, you get joules per second, which is also known as watts.


Difference between Watts and Amps?

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


How do i calculate how many watts does a dehumidifier use?

14.4 watts


How many volts does it take to make 4000 watts?

There is not enough information to answer your question directly... In order to determine how many volts it takes to make 4000 watts, you also need to know how many amperes there are. That is because watts is volts times amperes. For example, if you had a 120V system, you could divide 4000 watts by 120 volts to get 33 1/3 amperes.


Why kilo watts converted in kilo volts?

Kilowatts are never converted to kilovolts. There's no direct relationship between them, without involving other quantities in the circuit. Watts = (volts) times (amperes) Kilowatts = (kilovolts) times (amperes) Kilovolts = kilowatts/amperes
