An electrical conductor is a material that allows the flow of electric current. Most metals are good electrical conductors as their atomic structure allows electrons to move freely between atoms when a potential difference is applied. Conductors are classified into different types including plasma, semiconductors, and resistors, with plasma being the best conductor and resistors making electric current flow most difficult. Conductors are contrasted with insulators, which do not allow the passage of electricity. Common good electrical conductors include silver, copper, and aluminum, while materials like rubber, glass, and dry paper are typical electrical insulators.

2. What is an Electrical Conductor?
• An electrical conductor conducts
electricity. The ability to conduct
electricity is called electrical
conductivity.
• In an electrical conductor, the
electrical charges moves from
atom to atom when the potential
difference is applied across them.
• Most metals are electrical
conductors.

3. Types of Electrical
Conductors
1. Plasma – the best type of electrical
conductors.
2. Semiconductors – type of
conductors that can allow
electricity to flow through but not
as well as plasma electrical
conductors.
3. Resistors – type of conductors that
makes electricity flow very difficult.

4. Conductors VS
Insulators
• Conductors are materials that
allow electricity, heat, or sound
to pass through. Insulators are
the opposite. Insulators does
not allow passage of electricity,
heat or sound.
