If you have 14 watts, you have 14 watts of power. We measure electromotive force (EMF), which is commonly called voltage, in volts. EMF (voltage) is the force that will drive electron current flow, which is measured in amps. Simply put, power is current times voltage, or, said another way, watts is amps times volts. If you have 14 watts, you could have 14 amps at 1 volt, 7 amps at 2 volts, 2 amps at 7 volts, or any other combination of current and voltage with a product of 14. You may have picked up that because watts is amps times volts, we can say that a watt is a volt-amp. Extending that thinking, 14 watts is 14 volt-amps. There is no way to write 14 watts in volts, at least not without having a bit more information.

How you find ups watts?
It is expressed in Volt-Amperes not Watts.
The primary coil of a step-up transformer draws 110 W. What is the power provided by the secondary coil?
When we look at transformers, we'll generally see that watts in will equal watts out. Said another way, volt-amps in equal volt-amps out. There is a simple relationship between the turns ratio between the primary and secondary and the voltages between those two windings. From there, it's a hop, skip and a jump to figuring out currents. In a one to one transformer, volts in equal volts out. Current in will equal current out, too. Watts in will equal watts out. In a step down transformer with, say, a 10:1 ratio, 120 volts in will produce 12 volts out. And a 1 amp secondary current will appear as a 0.1 amp current in the primary. The 120 volts x 0.1 amps = 12 watts. And the 12 volts x 1 amp = 12 watts. Volt amps in equals volt-amps out, and power in equals power out. Simple and easy. If you are using a step up transformer in, say, a 110 volt to 220 volt application, 110 watts in the primary at the 110 volts will be 1 amp. In the secondary side, 220 volts will appear and 0.5 amps will be the current flow. The 220 volts times the 0.5 amps is 110 watts, as asked about. The secondary has twice the voltage and half the current of the primary side. There are 110 watts in and 110 watts out. Again, simple and easy.
How many watts in a 115 volt refrigerator?
How many Amps is the fridge pulling? Multiply the Amps by the 120V circuit you're plugging into and you'll get your Watts.
How many amps does a 110 volt 1.3 kw motor draw?
110 volts divided by 1,300 watts(1.3 kw) = .09 kw or 900 watts.
In a 240 volt single phase circuit A phase is 4000 watts B phase is 7000 watts what is the neutral load?
Question is incorrect. in a 240 Volt single phase circuit, how can you have A phase and B phase?
What does half a volt equal in watts?
You need to know amps to answer this... Amps x Volts=watts
How many watts does 115 volts equal im trying to find out how many amps does a 115 volt is equal to?
To find the number of amps in a circuit with 115 volts and a power rating in watts, you can use the formula: Amps = Watts / Volts. So, if you have a device that runs at 115 volts and consumes 575 watts, the amperage would be approximately 5 amps (575 watts / 115 volts = 5 amps).
100 watt is equal to how many va?
Since watts and volt-amps are different units of power, you cannot directly convert watts to volt-amps without considering the power factor of the load. In an ideal resistive circuit, 100 watts would be equivalent to 100 volt-amps. However, in practical applications with reactive components, the relationship between watts and volt-amps can vary.
4 ohms equals how many watts?
Ohms does not equal watts. You need to know what voltage is across the resistor to determine how many watts it is drawing or how many watts the resistor should be rated for.Power is the voltage across the resistor SQUARED divided by the resistance. If this 4 ohm resistor has 12 volts across it then the watts power is (12 x 12) / 4 = 36 watts.1 Watt equals 1 Volt times 1 Amp.
How many watts does a 3 amps use in America?
In America, the standard voltage is 120 volts. To calculate the wattage used by a 3 amp device, you would multiply the amperage (3 amps) by the voltage (120 volts) which equals 360 watts.
How many watts does my 12 volt 2 amp battery charger draw?
Your 12 volt 2 amp battery charger draws 24 watts of power (12 volts x 2 amps = 24 watts).
How many watts need for seven ampere's and 120 volt's?
770 watts.
How many watts in a Kva?
1 kVA is equal to 1,000 volt-amperes. The conversion between volt-amperes (VA) and watts (W) depends on the power factor of the load. For resistive loads and a power factor of 1 (unity), 1 kVA is equal to 1 kW (kilowatt). However, for loads with different power factors, the relationship between kVA and kW varies.
Watts equal to volt ampere?
In a direct current (DC) system, watts are equal to volt-amps. However, in an alternating current (AC) system, the relationship between watts and volt-amperes (VA) depends on the power factor of the system. The power factor is the cosine of the phase angle difference between the voltage and current waveforms.
How many amperes in a watt and how many watts in a volt?
Amps, volts and watts are interrelated, but you need to do a little math. Amps * Volts = Watts
How many watts in 1 ampere 230 volt?
Watts = Amps X Volts Grab your calculator!
How many watts does a 1000 watt 480 volt sports light draw?
A 1000 watt light operating at 480 volts would draw approximately 2.08 amps of current.
