Across
- 3. a circuit in which all parts are connected end to end to provide a single path of current.
- 4. a flow of electric charge that regularly reverses its direction.
- 8. a closed path in which electrons from a voltage or current source flow
- 9. an electrical cable which consists of multiple numbers of conductors with insulation sheaths placed in a single cable
- 11. Cable provided in wrapping of metal usually steel wires or tapes, primarily for the purpose of mechanical protection
- 12. helps those positive charges get to the ground in a safe, direct and controlled way, where they can be discharged without the risk of electrical shock or fire. It can be green, green-yellow or bare.
- 13. a box, usually of metal, containing one or more electric switches
- 14. a device that converts chemical energy to electrical energy
Down
- 1. in electrical circuits, it is the one that carries the electrical current. It is usually red or black.
- 2. carries the circuit back to the original power source, usually white or gray
- 3. constructed of one copper wire, either stranded or solid core, which is covered in PVC insulation and a cotton or rayon braid
- 5. a closed electrical circuit in which the current is divided into two or more paths and then returns via a common path to complete the circuit.
- 6. called a grounding receptacle because it allows a grounding wire to be connected from the electrical circuit to the appliance
- 7. a box, usually of metal, containing one or more electric switches
- 10. an electric current flowing in one direction only.
