Why are connecting wires/cables available in different sizes, colours or dimensions ?
Answers
Answer:
to differentiate positive and negative
1. Red wire - used to reveal the section conductor much like the terminal of a battery
2. Neutral wire - used to reveal the go back conductor much like the terminal of a battery
3. Green wire - used to reveal Earth connection.
Explanation:
Each colour has a purpose.
Black colour is normally used as an insulating electric cord.
These colourings suggest the voltage stage and section of the cord.
The smaller the cord diameter, the better the resistance there can be to the go with the drift of energy.
When one has excessive resistance, then they generate warmness that could become a hearthplace hazard.
Proper cord length is vital for any electric cord setup.
The cord length represents the diameter of the core conductor.
