Unit 7 Study Guide

A material that resists the flow of electrical charges.

• Conductor

• Insulator

• Wire

• Copper

A material that readily allows electric charges to pass through.

• Insulator

• plastic

• rubber

• Conductor

A path that is along which electric charges can flow.

• Closed Circuit

• Circuit

• Opened Circuit

• Electrical circuit

There are no breaks in its path

• Opened Circuit

• Electrical Circuit

• Closed Circuit

• Circuit

The path that is broken, and charges cannot flow.

• Closed Circuit

• Circuit

• Electrical Circuit

• Open circuit

A _________ controls the flow of charges by opening and closing the circuit.

• solar

• switch

• panel

• buttons

This has only one path for electric charges to follow. If any part of the path breaks, the circuit is open.

• series circuit

• open circuit

• parallel circuit

• closed circuit

A circuit with several different paths for the charges to follow. If one part of the circuit breaks, the charges can still flow along the other parts.

• series circuit

• opened circuit

• closed circuit

• parallel circuit

As electric charges flow through conductors, they produce ________.

• snow

• ice

• heat

• rain
