Why is electrical wiring usually made from copper?

• Because copper is shiny

• Because copper is not magnetic

• Because copper conducts electricity

• Because copper insulate electricity

What is an electrical circuit?

• lets you turn the energy on and off

• stop electricity from flowing through

• a closed path where where electricity flows

What is a circuit with several paths for electricity to flow?

• conductor

• parallel circuit

• series circuit

• open circuit

What is a circuit that only has ONE path for electricity to flow?

• series circuit

• parallel circuit

• light bulb

• closed circuit

An incomplete circuit is shown. To complete the circuit, a wire should be placed from —

• Point D to Point C

• Point B to Point C

• Point B to Point D

• Point A to Point D

This circuit has a battery, buzzer, and switch.When the switch is closed the buzzer will sound because -

• electricity can flow in a complete path

• the wires are cooled by the surrounding air

• the buzzer is made of special plastic

• the switch gives energy to the battery
