Across
- 4. a substance that heat or electricity can pass through or along
- 5. the pressure from an electrical circuits power source that pushes charged electrons (current) through a conducting loop, enabling them to do work such as illumining light
- 6. Circuit: has two or more paths for current to flow through
- 8. a measure of the opposition to current flow in an electrical circuit.
- 10. a device that stores chemical energy, and converts it to electricity
- 13. Diagram: a visual representation of a simple circuit and its main components
- 15. the flow of electric power or charge
- 16. a property that describes the extent to which a material opposes the flow of electric current through it
- 18. the equivalent of one volt per one amp
- 19. the unit of electric current
Down
- 1. a complete circular path that electricity flows through
- 2. a safety device in an electric plug or circuit
- 3. the ability to move heat or electricity from one place to another
- 4. the rate at which electrons flow past a point in a complete electrical circuit.
- 7. used to generate an electrical current
- 9. responds to an external force to mechanically change an electric signal.
- 11. Law: the voltage across a conductor is directly proportional to the current flowing through it, provided all physical conditions and temperature, remain constant.
- 12. Circuit: a circuit that is one with all the loads in a row
- 14. materials that do not allow electricity to pass through them
- 17. the unit of electromotive force
