Chapter 7 Electrical Energy

A path followed by an electric current

• open circuit
• flow
• current
• circuit

A complete electrical circuit or path through which electricity or current can pass or flow

• open circuit
• circuit
• closed circuit
• current

Material that allows electric current or thermal energy to pass through easily

• conductor
• insulator
• flow
• circuit

Flow of electricty in a wire or other conductor

• closed circuit
• current
• open circuit
• conductor

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

Which material would make the best conductor?

• paper
• copper
• glass
• wood

When plugged in, these lights will either be all on or all off.  Why?

• the bulbs will wear out all at once
• the electric current flows separately to each color bulb
• the electric current flows from one light bulb to the next
• the electric current flows cannot flow very easily through the bulbs
