Electrical Conductors
Objects that allow
electrical charge to flow
easily
Electrical Conductor Example:
The coil from a
electric heater
gets hot and
conducts
electricity well
Good Conductors
• Metal is a good conductor of
electricity
Property of Electrical Conductor:
In all good conductors
electric current flows
through them without
resistance
Example: Electricity

in the power line coils
without resistance
and easily
