Is there a difference between three phase and single phase electrical supplies?
Yes, there a difference between three phase and single phase electrical supply services.
Which rectifier type welding machine is better single phase or three phase as far as safety is concerned?
One is just as safe as the other. The deciding factor here is what supply voltage do you have at your establishment to operate the welder a single phase or three phase service.
What is phase difference?
A phase difference between two periodic signals is the time difference between two corresponding points on each signal. This time difference is usually measured in degrees or radians, but can be given as a unit of time as well.
Phase difference between voltage and current at resonance?
The power factor is a measure of the phase difference. If they are exactly in phase the PF = 1. If they are 180 degrees out of phase PF = 0.
What is the difference between a one phase and a three phase motor. And if a three phase motor is given a single phase supply will it run or not?
The difference between a single phase and a three phase motor is the amount of power conductors that feed the device. As to the other part of the question a three phase motor will not start or run on single phase. The phase angles on three phase are 120 degrees apart on a single phase system they are 180 degrees apart.
What is the relation between the path difference and phase difference?
Relation between phase difference and path difference is path difference/wavelength=phase difference/2*pi
Is there a difference between three phase and single phase electrical supplies?
Yes, there a difference between three phase and single phase electrical supply services.
How do you measure phase difference between 2 pendulums?
You can measure the phase difference between 2 pendulums by measuring the distance between the two. The amount it comes out to will be the difference.
What is the difference between cw and steady at lock-on phase?
What is the difference between cw and steady at lock-on phase? I don't know.
Which rectifier type welding machine is better single phase or three phase as far as safety is concerned?
One is just as safe as the other. The deciding factor here is what supply voltage do you have at your establishment to operate the welder a single phase or three phase service.
What is difference between a phase and a phase transition?
a phase is a region with homogeneous (uniform) properties and a conversion between states is called a "phase transition"
Single phase and three phase circuit?
Yes, there is a difference between single phase and three phase circuits.
What is the difference between nano anatase and nano rutile?
The difference in the crystal structure of the anatase phase and rutile phase
What is the difference between two phase and double sampling?
what is the difference betwee two stage and two phase sampling
What is the difference between energy investment phase and energy payoff phase?

What is the difference between frequency modulation and phase modulation?
The difference between frequency modulation and phase modulation is that with frequency modulation the angular frequency of the signal is modified while with the phase modulation, the phase angle of the signal is modified.
Why do you rate a dc machine in watt but a transformer in kilo volt-ampere?
The difference between watts and volt-amperes is due to the relative phase angle, or power factor, between voltage and current. In a DC system, the two are in phase. In an AC system, with only resistance, the two are also in phase. Add capacitance or inductance and the phase angle changes.
