The formula which are needed for making of a single phase transformer
i.e o/p voltage,watt,current,turn,core size,coil number,bobin size etc
Answer 1: TV's use single-phase power. Answer 2: TV's use single phase power of 220 or 110 volts ac power depending on what part of the world you live in.
Multiply the power of the load [1.732 x UL IL x power factor], expressed in kilowatts, by the operating time, expressed in hours. This is only practical for a constant load.
The formula is: current (in amps) = power (in watts) , divided by (240 times the power factor). The power factor is 1 for incandescent light or heaters, otherwise it can be assumed to be 0.75 for other loads.
There are several advantages of 3-phase power over single phase power. First, with 3-phase power, more power can be transferred with the same amount of wire (meaning the amount of copper used in all of the conductors transferring that power) as with single or 2-phase power. Also, power is transferred more "evenly" with 3-phase power because the "next peak" is closer than it is with single and 2-phase power. The 3-phase motors run more smoothly than those run on fewer phases. Also, there are motor design considerations (one being control of the direction of rotation) regarding the motor that make 3-phase power more attractive. Use the link to the Wikipedia article on 3-phase power and skim it. It isn't long and it is quite readable.
Electric power is measured in watts. It does not matter if it is single phase or three phase. All things being equal, for the same load, the power measured in a single phase circuit or a three phase circuit, will be the same.
Q = 3 Vph Iph sin(phase angle) = 31/2 Vline Iline sin(phase angle)
The phase constant formula used to calculate the phase shift in a wave is 2/ d, where is the phase shift, is the wavelength of the wave, and d is the distance traveled by the wave.
To convert single-phase power to three-phase power, you can use the formula: P = √3 x V x I x cos(θ), where P is the power in watts, V is the voltage, I is the current, and cos(θ) is the power factor. This formula assumes balanced loads.
To convert 2 kW to kVA in single phase, you need to know the power factor. If we assume a power factor of 0.8 (common for many single-phase loads), the conversion formula is kVA = kW / power factor. Therefore, for 2 kW at a power factor of 0.8, the result would be 2 kVA / 0.8 = 2.5 kVA.
Phase angle is defined as the angle by which the load current leads or lags the supply voltage in an AC circuit. There are numerous ways to calculate a circuit's phase angle, so there is no 'formula' as such. For example, if you know a load's resistance and impedance, or its true power and apparent power, then you can use basic trigonometry to calculate the phase angle, and so on.
Answer 1: TV's use single-phase power. Answer 2: TV's use single phase power of 220 or 110 volts ac power depending on what part of the world you live in.
For a single-phase system, active (or 'true') power is the product of the supply voltage, the load current, and the power factor of the load.

The formula for calculating the phase difference between two waves is: Phase Difference (2 / ) (x) Where: Phase Difference is the difference in phase between the two waves is the wavelength of the waves x is the difference in position between corresponding points on the waves
Multiply the power of the load [1.732 x UL IL x power factor], expressed in kilowatts, by the operating time, expressed in hours. This is only practical for a constant load.
More information needed - is it a network cable (ethernet) or a 2-phase power supply (unlikely) . .
To calculate the phase current of a 10kW 3-phase motor, you can divide the total power (10kW) by the square root of 3 (approx. 1.732) and then divide that result by the line-to-line voltage. The formula is: Phase Current (Amps) = Power (W) / (√3 x Line-to-Line Voltage (V)).
