Conductors and Insulators
Definition:
Conductor:
A conductor is a material that allows electric charge to flow through it easily.
Insulator:
An insulator is a material that does not allow electric charge to flow through it easily.
Examples:
Conductors (electricity flows easily):
• Copper
• Aluminium
• Iron
• Gold
• Silver
Insulators (electricity does not flow easily):
• Rubber
• Plastic
• Wood
• Glass
• Paper
Why are they important?
Conductors and insulators are important because they control how electricity flows, which keeps devices working and people safe.
Why conductors are important:
• They carry electric current from one place to another, like in wires.
• They let electricity move efficiently inside circuits so devices can work.
• Metals are used in plugs, chargers, and electronics because they conduct well.
Why insulators are important:
• They protect us from electric shocks by blocking the flow of electricity.
• They cover wires (plastic/rubber coating) so electricity stays inside the wire.
• They prevent short circuits by keeping different wires and components separated.
Simple idea:
Conductors move electricity where we want it to go,
Insulators stop electricity from going where it shouldn’t go.
