Across
- 4. An uncharged elementary particle. Present in all atomic nuclei except the hydrogen nucleus.
- 8. The flow of electrons from atom to atom in a conductor
- 11. CIRCUIT A circuit in which the parts are connected end to end, positive pole to negative pole, so that only one path is provided for current flow.
- 14. A testing device that can be set to read ohms (resistance), voltage (force), or amperes (current) of a circuit.
- 15. An instrument for measuring the flow of electrical current in amperes.
- 16. An instrument for measuring the force in volts of an electrical current. This is the difference of potential (voltage) between different points in an electrical circuit. Voltmeters are connected across (parallel to) the points where voltage is to be measured
- 17. A unit of electrical pressure (or electromotive force) which causes current to flow in a circuit. One volt is the amount of pressure required to cause one ampere of current to flow against one ohm of resistance.
Down
- 1. A unit of measure for indicating the electrical power applied in a circuit. It is obtained by multiplying the current (in amperes) by the electrical pressure (in volts) which cause it to flow.
- 2. A unit of measure for the flow of current in a circuit.
- 3. A circuit in which some of the circuit components are connected in series and others are connected in parallel.
- 5. A circuit in which the circuit components are arranged in branches so that there is a separate path to each unit along which electrical current can flow.
- 6. A substance or body that resists the flow of electrical current through it.
- 7. A device which converts mechanical energy into electrical energy
- 9. A tiny particle which rotates around the nucleus of an atom. It has a negative charge of electricity.
- 10. Movement of electricity along a conductor.
- 12. An instrument for measuring the resistance in ohms of an electrical circuit.
- 13. The standard unit for measuring resistance to flow of an electrical current
