Connecting wires are used to allow an electrical current to flow from one part of an electrical circuit to another. They are a vital component of any electrical circuit.
Here are some things to know about connecting wires:
-
Material
Copper is often used for connecting wires because it has low resistance, is affordable, and is easily available. Aluminum is another common material used for connecting wires.
-
Resistance
Connecting wires should have close to zero resistance.
-
Color coding
Wires are often covered with an insulated coating that comes in different colors. The color codes are used to distinguish between neutral, ground, and live wires. The color codes differ from country to country.
-
Transmission
Power cables can be used to transmit electrical power. They can be installed in buildings, buried underground, run overhead, or exposed.
