Electricity Vocabulary

3. A schematic diagram, in particular of an electric or electronic circuit.
6. The SI unit of electrical resistance, expressing the resistance in a circuit transmitting a current of one ampere when subjected to a potential difference of one volt.
8. Electrical connection of a circuit or conductor to the earth.
9. A container consisting of one or more cells, in which chemical energy is converted into electricity and used as a source of power.
11. A material or device that conducts or transmits heat, electricity, or sound, especially when regarded in terms of its capacity to do this.
14. The degree to which a substance or device opposes the passage of an electric current, causing energy dissipation.
15. A stable subatomic particle with a charge of negative electricity, found in all atoms and acting as the primary carrier of electricity in solids.

1. A device for making and breaking the connection in an electric circuit.
2. circuit A parallel circuit is a closed circuit in which the current divides into two or more paths before recombining to complete the circuit.
4. A quantity representing the rate of flow of electric charge, usually measured in amperes.
5. A substance or device that does not readily conduct electricity.
7. A machine, especially one powered by electricity or internal combustion.
10. current (AC) An electric current that reverses its direction many times a second at regular intervals.
12. current (DC) An electric current flowing in one direction only.
13. circuit A series circuit is a closed circuit in which the current follows one path.
