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 else can I help you with?
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 the effect on the supply current if the capacitor is removed?
It depends on how the capacitor is connected and whether the supply voltage is a.c. or d.c. Assuming you are talking about a power-factor improvement capacitor (connected in parallel with an inductive load, supplied with a.c.), then the supply current will reduce.
Power equals voltage times what?
In DC, power equals voltage x current. In AC, power equals voltage x current x power factor. The power factor is an adimensional constant, and in common circuits it is often close to 1.
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
350 watts 220 volts equals Current?
The formula you are looking for is I = W/E. Amps = Watts/Volts.
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.
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 to Divide 160 watts into 120 volts?
To find the current, use the formula: Power (W) = Voltage (V) x Current (A). Rearrange the formula to solve for current: Current (A) = Power (W) / Voltage (V). Therefore, 160 watts divided by 120 volts equals 1.33 Amps.
120 volts plus 500 watts equals how many amps?
The formula you are looking for is I = W/E. Amps = Watts/Volts.
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.
Hp equals 60 and volts equals 480 what are the amps?
746 Watts per horsepower / 480 volts x power factor x efficiency x 1.73 = amps assuming that the motor is three phase. 746 x 60 =44760 watts divided by 480 x 1.73 = 53.9 amps ( If the pf and eff. information is not known this will put you in the ball park)
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 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.
