Neutral Ground Resistor is using for minimizing the fault current of system.
It is a resistor which connected between ground and neutral and increase the resisting path for fault current.

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.
Why do some electric panel have ground and neutral bonded together?
By National Electric Code only the Main Panel should bond ground and neutral. If subpanels have ground and neutral bonded, it could cause ground loops and shock hazards.
Why does your panel have a neutral but no ground?
Just checked and it does have a ground connection.
What two colors may be used for the ground conductor neutral?
What two colors may be used for the ground conductor (neutral)
Is it OK illegal or dangerous to connect the neutral to ground to make the circuit work?
If you have to connect the neutral to ground to make the circuit work then you have an open neutral in your circuit. Be careful in handling the neutral as there can be voltage potential on the neutral if a load is connected. In a properly wired home that has been inspected by the local electrical inspector the neutral should be bonded to the ground at the main service distribution point. There will be a green screw that projects through the neutral bus and is threaded into the back of the electrical panel. This should be the one and only place in the whole electrical system where this neutral to ground connection takes place. Dangerous!!!!! The ground is the safety to prevent you from getting shocked due to a malfunctioning piece of equipment. By using the ground for a neutral you will be energizing the entire ground system of you house or business. Thus anything with metal on it and a ground wire going to it will be electrified if the ground fails at the breaker box or building ground rod. Do you want to take this risk? Not I..........
What is neutral grounding resistor panel?
A neutral grounding resistor panel is used to resist fault current to the ground. It is used for alternator protection protection purposes. When a fault occurs in the alternator, the panel helps force the current to the ground.
Why neatural ground resistor using in 33kv transformer?
The function of a neutral earth resistor is to limit any fault current resulting from fault between a line conductor and earth.

Difference between ground and neutral?
As i know,neutral is the return path of current & ground is for any leakage current

By National Electric Code only the Main Panel should bond ground and neutral. If subpanels have ground and neutral bonded, it could cause ground loops and shock hazards.

78xx regulater as a constant current source?
The 78xx regulater can be used as a constant current source, by connecting the output to the input side of a series resistor, and the "ground" to the other side of the resistor. Do not connect the "ground" to real ground - leave it floating.Since the 78xx maintains a constant voltage differential between output and ground, there would be a constant current through the resistor.
Why we use emitter resistance in circuits?
The emitter resistor is connected to ground(in the case of an rc coupled amplifier).Also input signal applied at the base is grounded.Then the emitter resistor forms a feedback to the input signal (through the ground return path).So emitter resistor is also called feedback resistor.
Why no electric shock from neutral line?
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.
When wiring a range the outlet has a neutral ground and 2 hots you have three wires do you put the bare wire in the neutral or ground on the outlet?
the bare copper is always a ground
