if we r talking about the power that is generated in powerhouses( i.e, source is not a D.C battery), one of the two terminals that comes out of the dynamo(of generator) is grounded near the generating plant itself. so theoretically speaking, ground and neutral are at same potential. so voltage diff between them would be 0.
but practically, ground is a term given to terminal that connects body of electrical appliance at home or industry directly into earth. this is done to prevent electrocution of any person handling it, just in case the body of appliance comes into contact with a live wire within the instrument(may be due to faulty wiring or normal wear and tear) and with probably defective neutral contact. Even in case of such a happening, if there is proper grounding, the voltage diff between them is 0.
What else can I help you with?
Why we don't get shock if we touch neutral wire..we need two wires to close circuit pH and n when circuit closes current will flow around the circuit and one wire gets shocked other not why?
We don't get shocked when we touch neutral and ground because neutral is grounded back at the distribution panel, so the effective voltage between neutral and ground is very low. It won't be zero, because there is current flowing on neutral, causing a voltage difference between the load and the distribution panel, but it is low enough, assuming there is no malfunction, to not cause a shock.In the case of touching hot and neutral, or hot and ground, you will get shocked because there is line voltage between hot and neutral, and because neutral and ground are connected together, there is also line voltage between hot and ground.Note, however, that connecting a load between hot and ground is a violation of the code and the intent of the design, because ground is not rated to carry current except in short term fault conditions - you must always connect a load between hot and neutral, or between hot and hot, as the case may be.
Why neutral ground voltage is 120v sometime 0v?
There should be no voltage on the neutral wire to ground. This is a serious situation. Call a qualified electrician to check this out.
Could the neutral point voltage be like phase voltage?
Yes,when the neutral potential is at ground potential i.e., 0v.
Does voltage on ground mean open ground?
Voltage on ground can mean an open ground. It can also mean (high) current on ground, due to a ground fault such as reversed neutral and ground.
Why current and voltage are not equal?
Current means flow of electrons Whereas the difference between two points is the voltage difference. Example: when you hold a filled jug of water at a certain height, it is the voltage. Because there is some difference of water at you end and the ground. But when you start pouring the water from the jug, water will fall on the ground which can be said a current.
Should there be voltage between the neutral and ground?
No, ideally there should be no voltage between the neutral and ground wires in an electrical system.
Could a neutral wire be powered?
There should be zero voltage between neutral and ground.
What is the significance of the neutral to ground voltage in electrical systems?
The neutral to ground voltage in electrical systems is important because it helps to ensure the safety of the system. When the neutral to ground voltage is at the correct level, it means that there is a proper connection between the neutral and ground wires, which helps to prevent electrical shocks and fires. Monitoring and maintaining the neutral to ground voltage is crucial for the overall safety and functionality of an electrical system.
What is the reading ground to neutral?
Ideally ground and neutral should be at the same potential, but as there is current in the neutral wire and no current (normally) in the ground wire there can be a difference. I have personally measured over 25 VAC on the neutral relative to ground in some systems.
Difference between ground and neutral?
As i know,neutral is the return path of current & ground is for any leakage current

What are the differences between voltage and potential difference?
Voltage is the potential difference to the ground. By convention, ground potential is zero volt.The above answer is incorrect. 'Voltage', by definition, is potential difference. It has nothing to do with being measured with respect to ground -in fact potential difference (voltage) cannot be measured with respect to anything.
How do you determine hot to neutral?
How do you determine what? If you are asking how do you measure the voltage between Hot and Neutral, I suggest a voltmeter. If you are asking how do you differentiate between Hot and Neutral in home wiring, the Hot is Black and Neutral is White.
Why neutral ground voltage is 120v sometime 0v?
There should be no voltage on the neutral wire to ground. This is a serious situation. Call a qualified electrician to check this out.
Why is it that when you touch the neutral in a box that is not connect to the panel cause the test light to come when touching the power wire?
It shouldn't. The open end of a non connected neutral should have the same potential as the voltage feeding the circuit. The only time a voltage will show is when the return neutral is tested with a meter to the neutral bar or the ground return bar. It will then show what the supply voltage to the connected load is. Once this neutral is connected to the neutral bar there will be no voltage shown across the test meter between the neutral and the neutral bar or the ground bar.
Should there be power from common to ground in wall socket?
120 volt wall outlets. Their could me a small voltage between neutral and ground,up to around 1.5 volts. What you are measuring is the voltage drop on the system at that point in the system. You see the neutral and the ground are at the same level some where up stream (service panel). The neutral is under the same load as the phase conductor, and the neutral will drop voltage same as the phase. This is in fact the way I measure voltage drop, (neutral to ground.) However don't get fooled by high imped. meter, They have a way of ghosting a voltage. Or floating high, You get a reading but the voltage is really not their.
How does an electric utility ground electricity delivered to your home?
Electricity is delivered to homes through transformers. The center of the transformer output winding is connected to ground. This center tap is then connected to the home power panel as the neutral lead. The voltage between the grounded neutral and either of the "hot" legs is half the voltage between the legs. In the US and Canada, the full voltage between the legs is 240V and between either leg and neutral is 120V.
