Topic 8 Energy Transfer in Electrical Systems

The presence and flow ofelectric charges.

Flow of electric charge in a circuit.

Cells that are connected together.

Provide a convenient way of controlling electrical energy systems.

Materials that resist the flow of charge. They cause energy to be lost as heat.

Low resistance parallel path.

List three effects of an electric current:

Resistance wire inside a light bulb that glows to produce light.

Solution with positively and negatively charged particles.

Electrical conductor used to make contact with a non-metallic part of a circuit.

A device used to protect components of a circuit.

The regions of force surrounding a permanent magnet or a moving charged particle.

Negatively charged sub-atomic particles.

Materials through which electrons can flow.

A chemical system that stores electrical potential energy.
