- 30. An instrument for measuring the properties of an electrical circuit
Down
- 1. A device that permits current to flow through it in only one direction
- 2. Wires cross without connecting so electrons cannot be shared
- 4. The center portion of an atom that contains protons and neutrons
- 5. Equal to the number of protons in the nucleus of an atom
- 7. Device used to limit or restrict the current in a circuit
- 8. Energy created as electrons collide and transfer from atom to atom
- 9. Wires all in contact so electrons can be shared
- 11. The opposition to the flow of the current
- 13. Electrons flow is difficult between atoms
- 17. Uncharged atomic particles
- 18. The force (pressure) behind the flow of current
- 20. The flow of electric charge
- 21. The electrical charge an object develops as a result of having an unequal number of protons and electrons
- 24. Mechanical device that connects or disconnects a component or circuit
- 26. Positively charged atomic particles
