Electrical Energy Lesson 9 IQWST PS2

What is energy transformation (conversion)?

• Energy transformation is the process of creating energy out of nothing.

• Energy transformation is the process of converting matter into energy.

• Energy transformation is the process of changing one form of energy into another.

• Energy transformation is the process of storing energy in a battery.

A device that makes electricity by using chemical reactions, stores energy until it is needed

• circuit
• battery
• insulator
• copper wire

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

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

Electricity is the flow of _______through a conductor. They can move from one object to another, causing the material to take on a temporary change.

• electrons
