The figure 1.73 is the results of the square root of 3. 1.73 is used in three phase calculations. The number is also used on three phase four wire systems. To find the coil voltages of a wye system 1.73 is divided by the phase voltage. An example, three phase 480 wye system. 480/1.73 = 277 volts

What is the formula for real power?
volts times amps equal watts, or 550 lbs per sec equals 1 horse power.
What is a combination of volts and amps?
Specifically, Volts and Amps would be called VA or volt amps, as in the rating of a transformer, but it is loosely referred to as Watts. In DC theory, Volts mulitplied by Amps equals Watts. In AC theory, that same equation exists but it includes power factor. If the power factor given is 1 (100%), then Volts mulitplied by Amps multiplied by Power Factor of 1 equals your Watts.
3 phase Motor watts to amps?
The formula you are looking for is, kW x 1000/1.73 x volts x pf (power factor).
How do you calculate hp from amps?
1 HP is 746 watts in principle. The power is in watts, and the power is the volts times the amps. For an AC motor the power is the volts times the amps times the power factor times a factor that depends on the power-conversion efficiency of the motor.
What is most important in dc power -volts-watts or amps?
You didn't define "importance" so it is hard to tell. They are all related by the formula Watts = Volts x Power Factor. Power Factor varies from zero to one. One thing that is often done in an application is to try to reduce the current and proportionally increase the voltage to obtain the needed wattage. That is why most electric stoves run at 240 volts rather than 120 volts, because 1/2 the current is required at the higher voltage; and you can use smaller wire and connect to a lower amperage breaker.
What is the formula for real power?
volts times amps equal watts, or 550 lbs per sec equals 1 horse power.
How many amps are in 280 watts with 120 volts?
W = Amps times Volts. A = W/V, A = 300/120 = 2.5 amps
When you applied 230 volt and current of choke is .43 amp then according to power formula the value is 99.82 watt while on tube light it is marked as 40 watt how it can be possible?
In an AC system the power is often less than the volts times the amps. The full formula is watts = volts times amps times power-factor. Some bulbs have a power-factor as low as 0.5.
What is a combination of volts and amps?
Specifically, Volts and Amps would be called VA or volt amps, as in the rating of a transformer, but it is loosely referred to as Watts. In DC theory, Volts mulitplied by Amps equals Watts. In AC theory, that same equation exists but it includes power factor. If the power factor given is 1 (100%), then Volts mulitplied by Amps multiplied by Power Factor of 1 equals your Watts.
How many amps equals 400 watts?
Watts = Amps x Volts x Power Factor. Power Factor = 1 for resistive loads and gets smaller for inductive loads like motors. Assuming home voltage of 120 Volts and a PF = 1 your answer is 400/120 = 3.33 amps.
How does kVA change as Power factor changes?
Power = volts x amperes x power factor. However, VA or kVA is simply the product of volts x amperes, and does not take into account the power factor. Note that in many practical situations, the power factor is close to 1.
350 watts 220 volts equals Current?
The formula you are looking for is I = W/E. Amps = Watts/Volts.
3 phase Motor watts to amps?
The formula you are looking for is, kW x 1000/1.73 x volts x pf (power factor).
What is the formula for finding out how many amps is required to achieve the full 100 watt output from a 9 volt bulb?
The formula is volts times amps equals watts, or watts divided by volts equals amps.
How many amp equals 1200 watts?
Watts = Amps x Volts x Power Factor Maximum value of PF is 1 for a resistive load. If you have 120 volts and a PF = 1, then amps = 10.
How many watts is 8 amps?
It's 120 x 8 for things with a power factor of 1, like electric heaters, irons or incandescent bulbs. If the item connected has a power factor less than 1, like electric motors, televisions, computers or CFL bulbs, you have to multiply by the power factor. <<>> The formula you are looking for is Watts = Amps x Volts.
700 watts at 110 volts equals how many amp?
The formula you are looking for is I = W/E. Amps = Watts/Volts.
