Energy & Motion 2

Has a complete path which allows electricity to flow continuously.

• closed circuit
• energy
• frequency
• battery

A device made of conducting material that can open and close an electrical circuit.

• friction
• switch
• pitch
• battery

An electrical cell that provides electricity or a power source for a variety of electrical devices. A source in an electrical circuit.

• closed circuit
• switch
• battery
• electromagnet

The part of a circuit that pushes electrical current from the conducting material along the path. Batteries are an example of this.

• variable
• wavelength
• wire
• source

A lamp or light source whose light is produced by the glow of a heated wire. This requires an electrical circuit to heat the wire. 

• simple circuit
• lightbulb
• wire
• source

The part of a circuit that uses electricity by giving off light, sound or heat, or increasing magnetic interaction. Lightbulbs, motors and electromagnets are examples of this.

• load
• path
• lightbulb
• variable

The part of a circuit along which electricity travels. Made of conducting material.

• kinetic energy
• circuit
• path
• source

The part of an electrical circuit that provides a path for the flow of electrons from the source (battery) to the load (lightbulb).

• switch
• friction
• sound waves
• wire

A break in the conducting material of the path. Electricity cannot flow continuously in this.

• gravity
• open circuit
• lightbuld
• simple circuit

The flow of electrical charge through a wire or another conducting material. 

• current electricity
• collision
• energy transfer
• vibrations
