Your question should read, 'Why does a neutral have zero potential?' 'Voltage' means 'potential difference', and you cannot have a potential difference at a single point.
A neutral doesn't necessarily have zero potential although it is connected to earth (ground). This is because the potential of earth isn't literally zero; it's just considered to be zero, in the same way that sea level is considered to be zero in terms of height. Furthermore, there is often a voltage drop between the neutral and earth -in which case, the potential of the neutral can be several volts higher than the potential of earth.
Zero, or very close to it. If there is a large neutral current flowing, voltage drop on the neutral leg could cause a volt or so to read between the two. If you read full line voltage, the outlet is wired wrong!
Geez, because it is just that; A NEUTRAL EARTH, there should be equal potential on each side, therefore no current flow, and no voltage.
Zero. If voltage starts at zero at zero degrees, it rises to peak voltage at 90 degrees. Voltage then reaches zero at 180 degrees and heads for negative peak voltage at 270 degrees and then back to zero at 360 degrees.
Zero Voltage switching is a standard used to describe electrical appliances which turn on or off only when the output voltage is Zero.
There is normally no voltage on the neutral line because the neutral line is grounded. However, and this is always important, do not assume that neutral is grounded, nor that there is not an elevated voltage on neutral or ground due to a possible ground fault.
There should be zero voltage between neutral and ground.
You really should be asking why the potential of neutral is zero. 'Voltage' means 'potential difference' which, by definition, cannot exist at at point. The reason is that the neutral conductor is earthed (grounded), and earth is, by general consent, considered to have a potential of zero volts. In practise, however, there is usually a small voltage drop between the neutral and earth, so it would be more accurate to say that the neutral's potential is close to zero.
In a three phase connected system, if the loads are not balanced or if one voltage is disconnected due to any reason there will be neutral displacement to a new voltage level (from normal zero voltage). This can increase/decrease voltage in other phases
Neutral earthing are grounding options available for both low and medium voltage power systems. It provides point of zero volts.
leave the brushes of the motor at the position where the induced voltage is zero

In a typical residential situation there is 220 to 240 volts between the two hot wires that are typically red and black and 110 to 120 volts between neutral and either black or red. The voltage between neutral and earth should be zero.
Geez, because it is just that; A NEUTRAL EARTH, there should be equal potential on each side, therefore no current flow, and no voltage.
Between Neutral and Ground should be zero volts. Between Neutral and Hot should be 110 to 120 V in the USA, within the European Union it should be 230 V ± 6%.
This question is not quite clear but I will try it somehow. The voltage drop between the live and neutral, and live and earth will both be 230v, but the voltage drop between the neutral and earth is almost zero due to the fact that the neutral and earth is basically one conductor split.
The neutral conductor is bonded to ground, and is therefore always at earth potential, which is the zero-reference for voltage.
