it may be positive or negative
hope this helped :)
There is nothing to save. When the neutral wire becomes disconnected the equipment just stops operating. Disconnect the power supply, reconnect the neutral and the equipment will start operating again.
It has a neutral charge.
Presumably, you are asking the purpose of a neutral conductor, rather than 'contactor'?A alternating-current supply has two conductors, a lineconductor and a neutral conductor. The line conductor is at system potential (e.g. 230 V in Europe), whereas the neutral conductor is at approximately earth (ground) potential because it is earthed (grounded) at the supply transformer. The neutral conductor acts as the 'return' path to the transformer, carrying the same load current as the line conductor.
Gender-neutral diction allows both the masculine and feminine genders to participate in any given situation.

To determine if a metal leaf electroscope is neutral, bring a charged rod near the metal cap. If the metal leaves diverge, the electroscope is neutral. If the metal leaves collapse or diverge more, the electroscope is positively charged.
The rod is charged. The leaves of the electroscope move apart due to electrostatic induction, where the negative charges in the leaves are repelled by the negatively charged rod, causing them to separate.
If a negatively charged rod touches a neutral electroscope, electrons will flow from the rod to the electroscope, causing the electroscope to become negatively charged. The leaves of the electroscope will repel each other, indicating a charge has been introduced.
When a negatively charged rod touches a neutral electroscope, electrons transfer from the rod to the electroscope, causing the electroscope to become negatively charged. This results in the leaves of the electroscope repelling each other and spreading apart, indicating the presence of an excess negative charge.
When the probe of the electroscope is brought near a charge, free charges in the electroscope rod are either attracted to or repelled from the probe. This leaves a net charge at the other end of the rod (since the electroscope as a whole is electrically neutral). Since the other end of the rod is charged, its parts repel each other (since like charges repel). Thus, the gold-leaf indicators spread apart.
Electroscopes detect electric charge by the motion of a test object due to the Coulomb electrostatic force. The electric potential or voltage of an object equals its charge divided by its capacitance, so electroscopes can be regarded as crude voltmeters. The accumulation of enough charge to detect with an electroscope requires hundreds or thousands of volts, so electroscopes are only used with high voltage sources such as static electricity and electrostatic machines.
If you touch the knob of a positively charged electroscope with a negatively charged object, the excess electrons from the negatively charged object will flow to the electroscope, neutralizing the positive charge. The electroscope will become neutral or slightly negatively charged as a result.
If an electroscope is not charged, its leaves will remain in a neutral position, hanging straight down. This is because there is no excess charge to cause the leaves to repel each other and spread apart.
The sphere of an electroscope is always neutral at first. Let's say a negative ebonite rod is brought close but not touching the sphere. (The entire electroscope is neutral). The electrons in the electroscope will want to repell the electrons in the rod so the electrons in the electroscope move down into the 2 leaves and then repell because there is a high concentration of negatives. When the ebonite rod is removed, the leaves go back to their straight position. The electroscope is always neutral but only a charge distibution occured. The number of protons and electrons remain the same. However if a charged rod touches the sphere then the electroscope will be charged because it a conductor and the charge from the rod transfers to the electroscope because the rod's caharges want to attarct to the electroscope's opposite charges. This is called charging by contact.
If the electroscope is not charged, the leaves will remain in their neutral state, hanging down vertically due to gravity. When a charge is introduced, the leaves will either repel or attract each other, depending on the type and amount of charge applied.
A neutral substance acquires opposite charge to the object brought near it. For example, if a negatively charged object is brought close to a neutral substance, it will induce a positive charge on the neutral substance through the process of electrostatic induction.
The word neutral is an adjective. It describes someone who is not taking sides.
