because all wires have different work. one carry positive charge, one carry nagative charge,and one is nuetral.
they are of different colours because from this it can be easy to recognise the wires
What else can I help you with?
Are electrical cords and cable wires for computers TV cable boxes insulated?
Yes, of course they are insulated. If they were not the signals would short out and be unusable. If electric power cords were not insulated they would short out and blow the breaker (or worse start a fire)!
Can a type SE cable with an insulated neutral be used to feed an electric range through a sub-panel?
check your local codes for this
Why does a hairdryer not need a cable with an earth wire?
Hairdryers often have a double-insulated design, which means they have an extra layer of insulation to protect against electric shocks. This eliminates the need for an earth wire in the cable because the double insulation provides adequate protection against electric leakage.
What is pilc cable?
Paper Insulated Lead Sheathed Cable. Used for medium voltage levels.
What is the difference between insulated wire and ordinary cable?
Insulated wires and cables are commonly used conductors in power engineering
Service entrance cable underground feeder branch circuit cable mineral insulated cable jacketed cable?
These are different types of electrical cables used for various applications. Service entrance cable is used to connect the utility power to a building's main electrical panel. Underground feeder branch circuit cable is used for underground wiring between buildings or from the main panel to subpanels. Mineral insulated cable is a type of fire-resistant cable used in high-temperature environments. Jacketed cable refers to any cable with an outer protective covering for mechanical and environmental protection.
What will happen to electrical cable inside water?
If the electrical cable is not properly insulated, it can short circuit or cause an electric shock if it comes into contact with water. This can potentially lead to damage to the cable, fire, or injury to individuals nearby. It's important to keep electrical cables away from water to prevent these risks.

What is the difference between Type AC Cable and Type ACT cable?
ACT has thermoplastic insulated wires. AC is old MC is the modern cable.
What is difference between cable tray and cable trunks?
Cable tray is a system of wiring in a building in which insulated electrical wires are used to distribute power and communication to various access points. Cable trunks are power supply lines that are used to distribute power and communication services to large areas such as industrialized cities.
Which type of distortion occurs when a connection cable is inadequately insulated?
Impulse noise
What is the difference between an electric cooker cable and a bulb cable?
An electric cooker cable is designed to handle higher power loads and is typically thicker and more robust compared to a bulb cable which is thinner and designed for lower power applications like lighting. Additionally, an electric cooker cable may have different connectors and insulation ratings as it is meant for higher temperature environments.
