Divide the circuits amperage into the volt amps and you will get the voltage.
It depends on how much current it's putting out. An inverter rated at 800 volt-amperes can deliver 220 volts at 3.636 amperes, or it can deliver 110 volts at 3.727 amperes.
To determine Watts from Volts, you also need to know the current in Amperes (A) using the formula: Watts = Volts x Amperes. Therefore, 200 Volts alone cannot be converted into Watts without knowing the current. For example, if the current is 10 Amperes, then the power would be 200 Volts x 10 Amperes = 2000 Watts.
Amps, volts and watts are interrelated, but you need to do a little math. Amps * Volts = Watts
10000 watts / 220 volts = 45.4545 amperes
Power requirements are measured in KVA, which stands for Kilo-Volt-Amperes. To calculate the amount of power you require you would use the following formula. KVA = Volts * Amps / 1000
Divide Watts by Volts ; this gives you Amps.
To calculate the amperes for a fluorescent lamp using VA (volt-ampere), you can divide the VA rating by the voltage of the lamp. The formula is: Amperes = VA / Voltage. For example, if a fluorescent lamp has a VA rating of 60 VA and operates at 120 volts, the amperes would be 0.5A (60 VA / 120V).
The secondary winding's current rating is the rated apparent power of the transformer (expressed in volt amperes) divided by its voltage rating (expressed in volts). This applies to both step down, and step up, transformers.
To calculate the amperage, use the formula: Amperes = Watts / Volts. In this case, 55 kW is 55,000 watts. So, Amperes = 55,000 watts / 460 volts ≈ 119.57 amps.
Volts is the unit measurement for voltage Current is amperes or amps for short Resistance is ohms
To calculate the power in watts, you will also need to know the current in amperes. The formula to calculate power is P (watts) = V (volts) x I (amperes). If you only have the voltage (30 volts) and not the current, you cannot determine the power in watts.
Electric current is measured in amps not voltsElectric voltage is measured in volts.
