Material that slows down or stops electric current or thermal energy from passing through

• flow
• open circuit
• insulator
• conductor

A circuit or electrical path that is broken or incomplete so electricity cannot flow through it.

• open circuit
• conductor
• insulator
• closed circuit

Look at the diagram. What is the term for "B"?

• Wire

• Switch

• Resistor

• Voltage source/Battery

An example of a conductor of electricity is

• rubber

• plastic

• glass

• copper

Why is electrical wiring usually are covered with a layer of plastic?

• To make it look pretty

• To help electricity flow along the wire

• To make it safe

• To add more energy

Why is electrical wiring usually made from copper?

• Because copper is shiny

• Because copper conducts electricity

• Because copper is not magnetic

• Because copper insulate electricity
