The neutral provides a path back to the source for the electricity. In a three-phase circuit, it is mainly used to carry the unbalanced load back to the source. In theory, a perfectly-balanced three-phase circuit would not need a neutral, but this is almost impossible to achieve in actual practice.
An electric shared neutral is the white or negative wire that is shared between two electrical circuits on a basic single phase system. Most electrical devices use 120 volts and require a "hot" wire and a neutral wire to operate. Some larger devices use 240 volts and require two "hot" wires to operate. Two circuit breakers in an electrical panel can share one neutral wire as long as the breakers are not on the same "leg" of power. When looking at an electrical panel there are usually two "legs" of power feeding all the breakers, each leg has 120 Volts to ground, if the "legs" are combined you will have 240 Volts. A neutral wire can be shared by two circuits as long as the breakers are on separate "legs". If someone needed to add two circuits in their home, the could run what is called a 3-wire romex, It has a black wire, a red wire, a white wire and a ground wire. The white wire is the neutral for both the black and red 120 volt circuits, and the breakers for the new circuits would need to be on separate "legs" in the panel.
Yes, this is done on star (wye) systems where one neutral is used for three phase wires. e.g. 120/208 voltage system.
Two wires are always needed to supply electrical equipment so that the current has a complete circuit to flow in. One of the wires is earthed at the supply transformer, that one is called the neutral, and the other one is the live.
Ground and neutral should only be connected at the main electric panel to prevent parallel neutral currents. If it is a new installation, you must provide four wires (two hots, 1 neutral, & 1 ground) and connect to the four separate (appropriate) places on the dryer. If it is an existing installation and it only has three wires (two hots and a neutral) connect the neutral to both the neutral and ground connection of the dryer (the National Electrical Code allows this exception for older homes). Call a qualified electrician to do any electrical work.
Neutral wires are actually ground wires. They enable the circuit to be completed.
Black
circuits are made by connecting wires to an electrical resource and the electricity travels through and powers your electric device.
Insulation can be put over wires to prevent short circuit breaker trips.
It's not clear what exactly you mean. You can run two neutrals next to each other as long as you otherwise abide by electrical codes regarding the limits of conductors in an enclosure and gauge size. You can also use a single neutral return for two circuits if those two circuits are opposite phase, since the net result will be that the neutral never carries more than a single circuit load and may sometimes carry less or even nothing if both circuits are in use.

Ground wires, conductors, or circuits ARE NEVER FUSED. Fuses and circuit breakers are put in the wires and conductors supplying electrical current TO devices needing electrical power, and ARE NEVER PLACED IN the ground portion of the circuit between the electrical power consuming device, and the battery negative terminal.
The "hot" wire between these two coloured wires will be the blue one. The green colour is always used as ground in electrical circuits.
Closed circuits work, they have all the wires connecting from the battery, the switch and the lightbulb that is needed for the electrical current to flow through the battery through the closed switch into the light bulb and back into the battery. Therefore it works.
