There must be a 'return' connection if the load is to work. So, you cannot simply connect the load to the line conductor and expect it to work. It must also be connected to the neutral. In some circumstances (e.g. with no ground-fault interrupter installed), it will also work if you connect it to earth (ground) instead of the neutral, but this will contravene most electrical regulations and should NEVER be done.

How you differentiate between single phase and three phase transformer?
A single-phase transformer works with a single-phase supply, while a 3-phase transformer is used with a 3-phase supply. A single-phase transformer has 2 wires on the primary and secondary (ignoring taps) while a 3-phase tansformer has 3 or 4 wires on the primary and secondary.
Is air conditioner works on 1 phase and how it works on 3 phase also?
If an air condition is single phase, then it can only be connected to a single phase source. Since any two legs of a three phase source are considered single phase, there is no conflict, except to note that the individual phases of the three phase source match the voltage requirement of the air conditioner.
How three phase induction motor works without stator?
with 3 phase the rotating field is already set up when power is supplied with single phase you use a capacitor and a second winding to set up the rotating field
How do you convert a 3-phase power supply to a single phase supply?
The simplest answer is that the electric utility uses a transformer across 2 of the 3 hot leads to develop a single hot lead with an earth reference. What follows below is frequently edited by both amateurs and professionals, with mixed results. Wikipedia is a better source of more detailed information on this subject, in part because the article on three phase power has pictures.
How do single phase motor self starting?
it have a water container. the water pressure in the container varies the self starter works.

Convert single phase to three phase formula?
One common method to convert single phase to three phase power is by using a rotary phase converter. The rotary phase converter works by using a single-phase power source to generate a third phase, creating a balanced three-phase output. It typically involves using capacitors and an electric motor to create the additional phase needed for three-phase equipment.

Can you convert a three-phase motor to a single-phase motor?
Use only one of the legs (L1-L3), and the neutral. Some three phase circuits don't have a neutral. If that is the case, then you cannot run single phase.CommentYou don't need a neutral, providing the voltage is appropriate, you can get a single-phase supply by connecting the load between any two lines.
Can you change the wiring of a single phase appliance of 2.4 kw that works on 240 to 400 volts 3 phase 60 hz supply?
No, you can not you change the wiring of a single phase appliance of 2.4 kw that works on 240 to 400 volts 3 phase 60 Hz supply. They are two different electrical systems.
How the single phase load works on same voltage- two phase supply?
Two-phase supplies are very unusual these days, and describe an a.c. system in which the two phase voltages are displaced by 90 degrees. So you are probably thinking of a split-phasesystem.A split-phase system is created using a transformer with a centre-tapped secondary winding. The centre tap is grounded (earthed) and provides the neutral terminal. The outer terminals (labelled X1 and X2) supply a potential difference of 240 V between them, while terminals X1 to neutral and X2 to neutral each supply potential differences of 120V.

How convert 1 phase to 3phase in aircraft?
The power is generated in the form of three-phase in aircraft, and this sytem has no problem in feeding single phase loads. To conserve mass in tansformers and motors the supply works at 400 Hz.
What type of slide works best with phase-contrast microscopy?
Hanging drop can be observed for longer periods of time without drying out.
When three single phase tronsformer is conneted to star what will be the phase shift between each phases?
When 3ph transformer of required capacity is unavailable in that place 3 single phase bank is used. More over this bank works well in conditions where there's unbalance of loads. When there's quite small 3ph load you can isolate one transformer to create open delta connection. In bank nd single 3ph transfo's there wont be any change in maintaining phase shift
