Electricity Concepts

Intermediate

1. Electricity is a flow of energy through a source and through a receiver in a closed path.
2. Electricity can be transferred from a source to a receiver. A closed circuit creates a transfer of electricity, an open circuit does not.
3. A switch is used to open and close a circuit.
4. A fuse or circuit breaker opens a closed circuit for protection when a circuit overheats.
5. Light bulbs in a series circuit will go out if one is unscrewed.
6. Light bulbs in a parallel circuit will remain lit when another is unscrewed.
7. Electricity in circuits can produce light, heat, sound, and magnetic effects.
8. Electrical energy can be produced from heat, light, magnetism, and chemical energy.
9. Electricity flows easily through a conductor and flows with difficulty in a conductor.

Middle School

1. Electricity is the flow of electrons through a closed circuit that contains at least one source, receiver, and conducting path through which the electrons flow.
2. Electrical energy is the attraction or repulsion of charges.
3. Electricity and magnetism can exert a force on each other. Resistance reduces the flow of electricity.
4. The flow of electricity is related to the charges and the resistance (Ohm's law).
5. The flow of electricity in a series circuit is like ...
6. The flow of electricity in a parallel circuit is like...
