Electricity

2. An electric battery is a device consisting of one or more electrochemical cells with external connections provided to power electrical devices such as flashlights, smartphones, and electric cars.
5. a stable subatomic particle with a charge of negative electricity, found in all atoms and acting as the primary carrier of electricity in solids
6. a thing or substance used for insulation, in particular
7. the degree to which a substance or device opposes the passage of an electric current, causing energy dissipation. Ohm's law resistance (measured in ohms) is equal to the voltage divided by the current
11. The ohm is the SI derived unit of electrical resistance, named after German physicist Georg Simon Ohm
12. a material or device that conducts or transmits heat, electricity, or sound, especially when regarded in terms of its capacity to do this.
13. Components of an electrical circuit or electronic circuit can be connected in many different ways. The two simplest of these are called series and parallel and occur frequently
15. an electric current flowing in one direction only

1. a flow of electricity which results from the ordered directional movement of electrically charged particles
3. an electric current that reverses its direction many times a second at regular intervals, typically used in power supplies.
4. a machine, especially one powered by electricity or internal combustion, that supplies motive power for a vehicle or for some other device with moving parts
8. a schematic diagram, in particular of an electric or electronic circuit
9. an electrical component that can "make" or "break" an electrical circuit, interrupting the current or diverting it from one conductor to another
10. Components of an electrical circuit or electronic circuit can be connected in many different ways. The two simplest of these are called series and parallel and occur frequently
14. electrical connection of a circuit or conductor to the earth
