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.
What else can I help you with?
What would the results of voltage drop test be if the circuit is open?
voltage drop is zero bcz in open ckt current will be zero
What is the voltage of the neutral wire in an electrical circuit?
The voltage of the neutral wire in an electrical circuit is typically close to zero volts.
Could a neutral wire be powered?
There should be zero voltage between neutral and ground.
What is the voltage level typically found in a neutral wire?
The voltage level typically found in a neutral wire is close to zero volts.
Why neutral have zero voltage?
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.
What is the advantage of parallel circuit from serios circuit?
In parallel ckt voltage in all branches will be same, its different in series ckt
How do calculate voltage drop in a circuit?
for calculating the voltage drop in ckt first of all you have to calculate the total resistance of the ckt as well as total current also then applying ohm's law v=IR u can calculate the voltage drop across a ckt While the answer is correct you might investigate thevenin theory.
How the Neutral displacement occures?
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
Relation between voltage and current if you consider capacitor ckt?
In a capacitor ckt, current will be lead ahead from voltage by an angle 90 degree. Because for a capacitor the relationship between voltage and current is given as v=(jx)i , where v= voltage i= current jx=capacitive reactance
What is neutral earthing?
Neutral earthing are grounding options available for both low and medium voltage power systems. It provides point of zero volts.
How do you locate the neutral brush position in a dc motor?
leave the brushes of the motor at the position where the induced voltage is zero
Why short circuit and open circuit are equivalent appropriate?
In circuit equivalence, voltage and current sources are respectively equated to short and open ckt because of the very nature of them. A voltage source has zero internal resistance and current source has infinite internal resistance hence their equivalents:-)
