Can you use two Electric wire of 2mm in place of one wire of 4mm for the same load?
Arvind134
Do you remember basic arithmetic? Do you remember pi r square. If the diameter is 2, the radius is 1. If the diameter is 4 the radius is 2. Now 1 squared is 1. 2 squared is 4. So using the formula pi r squared tells us that a 4 mm piece of wire has 4 times the diameter as a 2 mm piece of wire. So two 2mm pieces of wire would have the equivalent of 1/2 the diameter and 1/2 the electricity carrying capability of a 4 mm piece of wire.

Why neutral wire doesn't give electric shock?
The neutral wire doesn't give an electric shock because it is the same potential as ground. That being said if you come in contact with the "hot" wire and the neutral or ground wire, you become the load and will receive a substantial shock.
Why do electric appliances have green wire?
The green wire is designated as a ground wire. This wire in a feeder cable is bare copper and connects to the distribution panel's ground bus and at the load it is connected to the frame ground of the equipment. The UK uses the same colour for the grounding or earthing but it also has a yellow tracer on the green colouration.
What happens when you connect the line wire from the switch to the load wire from the wall?
This is what the purpose of a switch is. It connects the "hot" wire to the load. When this is done the load becomes energized.
Why is the ground wire smaller in your 8 2 with ground wire?
The grounding wire is not intended to be a load-carrying conductor in ordinary use, but rather a SAFETY conductor. Grounding wires are often "one size smaller" than the associated load conductors in the same cable.
Do you need a neutral wire for a light to work?
The neutral wire is the return wire back to the distribution panel from the load. Without this return wire no load will work.

What size electric wire for 28 amp load?
AWG # 10
How can you make the electric circuit?
Anything with a voltage power source, connecting wire and a load is an electric circuit. Hence if you have a flashlight you have an electric circuit.
What happens to the electric current in a wire when voltage is increaced?
If the load resistance is constant, then increasing the voltage will increase the current by the same proportion -i.e. doubling the voltage will double the current.
What size of aluminum wire 3 stranded is used to run electric from house to dock?
Wire is sized by the amperage of the load. Without knowing what the load amperage,the voltage and whether the load is three phase or single phaseat the dock, an answer can not be given.

Is a wire thick with low electric resistance?
A wire that is thicker than another wire of the same material has less resistance
Does size of electric wire change the electric consumption?
Well, a thicker wire will have less resistance; a longer wire will have more resistance. However, in practice, and for practical reasons, the resistance of the wires is small, compared to resistances designed as such, or to any electric motor attached, or any other device that uses the electricity. Or, to summarize, it does not change the consumption. The consumption depends on the connected device, not on the wire. <<>> The size of the wire is governed by the load amperage. The higher the load amperage the higher the wattage and therefore more wattage consumption.
Why electric current across a wire drops?
Electric current does not drop. Electric voltage, however, drops across a wire because the wire has non-zero resistance. (Do not confuse electric current with electric voltage - they are not the same.)The reason current does not drop is that, in a series circuit, according to Kirchoff's current law, the current at every point in a series circuit is the same.
Inventor of electric wire?

How do you tell which is the line wire and the load wire?
The line wire will be hot and carrying power when the breaker is on. The load wire will not be hot and will have no voltage on it until it is connected with the line wire.

This is what the purpose of a switch is. It connects the "hot" wire to the load. When this is done the load becomes energized.
