How many amps in 15KVA circuit at 440 volts?
it is 15000/440 based on basic power definition i.e., power =voltage *current
How many watts is equal to 4.3 amps at 230 volts?
In normal simple circuits WATTS = VOLTS x AMPS So if you use a 12V car battery 4 amps is 48 Watts American 110V mains 4 amps = 440 Watts English 240V mains 4 amps = 960 Watts
How many watts equal one amp at 440 volts?
Watts = Amps x Volts x Power Factor Power factor varies from 0 to 1 with 1 being a pure resistive load like a light bulb. A motor would have a lesser value. So if your load is resistive just use 1 x 440.
What capacity of transformer required for step up from 220 to 380 3 phase 45 kw air compressor?
we are looking to wire up diagram for a 45kw transformer from 220 volts to 440 volts 3 phase 60 Hz <<>> The formula you are looking for is KVA = Amps x Volts x 1.73/1000 = 118 x 380 x 1.73 = 77573/1000 = 77.5 KVA transformer. Your primary amperage will be 205 amps and the secondary amperage will be 118 amps.
How do you prevent damage to equipments when 215 volts becomes 440 volts?
and breakers that can only hold up to 250 volts
How many amps will an electric heater use if 440 volts are applied to it and the resistance is measured at 80ohms?
The formula you are looking for is I = E/R. Amps = Volts/Resistance.

A circuit whose resistance is 22 ohms and has an applied voltage of 440 volts will draw a current of?
20A By using V=IR

How do you convert 440 Amps to KVA for three phase system?
You must rephrase your question to make it more specific. <<>> The formula to use to find KVA in a three phase system is, KVA = Amps x Volts x 1.73/1000.
What is the cable size for motor 15kw 440 volts connection?
The current draw is about 27 amps. A motor feeder has to be 125% of the motors full load amperage. 27 x 125% = 33 amps. A #8 copper conductor with an insulation factor of 90 degrees C is rated at 40 amps.
How do you get single phase 440 from three phase 440?
You Don't. 440volt 3-phase is actually 480 volts, taking a single phase gives 277Volts single phase. To get single phase 440 you would use one leg of three phase 440/760 three phase power.
What current flows through a hair dryer plugged into a 110 volt circuit if it has a resistance of 25 ohms?
Ohm's Law: Current is voltage divided by resistance110 volts divided by 25 ohms is 4.4 amperes. This is also 440 watts, which sounds low in today's design of hair dryers, leading one to think that the 25 ohms is incorrect or was measured incorrectly.

How can change voltage from 440 v 3 phase to 208 v 3 phase?
I have 12 amps 208/3/60 what would the amps be @ 440/3
