Yes, in most cases it is the white wire. (the black or red wire is the hot and the bare wire is the ground.)

How many circuits can share one neutral?
Yes, this is done on star (wye) systems where one neutral is used for three phase wires. e.g. 120/208 voltage system.
What is the need for neutral wires in circuits for electrical services?
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.
Buss in electrical?
Although 'buss' is widely used, particularly in the United States, the correct spelling is 'bus'. It is derived from the word, 'omnibus', meaning to 'serve all'. 'Bus' is a contraction of 'busbar', which is a metal conductor, often of rectangular cross section, and provides a common point of connection ('serving all') between several circuits. For example, the various circuits in an electrical panel are all connected to the input circuit using a busbar. One busbar is required for each line in a three-phase system, and another is required for the neutral. Yet another is required for the protective (earthing) system.
What is the element that is used to make permanent magnets and United States coins?
Iron
How many volts is used in toaster?
In the United States toasters run on 120 volts.

Is Lindsay a male or female name?
Lindsay is a gender-neutral name that can be used for both males and females. It is more commonly used as a female name in the United States, but it can also be found as a male name.
What do the different colors on household electical wiring signify?
In the United States, household electrical wiring typically uses one black and one red conductor to distinguish the ungrounded or hot conductors. This serves no purpose other than to be able to identify one wire from the other at each end. In any singe phase system, such as a home, on a 220v circuit, it matters not what position each conductor is terminated. On branch circuits, black is generally used on all 110v circuits, and a combination of black and red are used on all 220v circuits. White is used to identify the grounded or neutral conductor. And the green or bare conductor is used for the equipment grounding conductor, commonly called "the ground."
How many neutrals for three-phase multi circiuts?
For a three phase distribution system there is one neutral. In North America the electrical code allows three individual branch circuits to connect with one neutral as long as the three circuits each use an individual phase leg. This differs from 120/240 volt single phase wiring where only two legs can be used with one neutral.
Which wire used for ordinary light bulb?
In most home wiring circuits, the black wire is used to power a light bulb. The other wire is white and is called the neutral conductor.

What happened in the nazi war?
That was World War Two. The United States remained neutral until Japan attacked Pearl Harbor in 1941. Germany, Japan and Italy composed the axis that was fighting the allied side. The United States sent the army to Europe while the marines had the Pacific. The war ended when the United States used nuclear weapons in Hiroshima and Nagasaki on August 6 and 9, 1945.

Can parallel circuits be used instead of fuses?
No. Parallel circuits are not fuses. Fuses can be used to protect parallel circuits.
