Flashcards do conjunto (17)
- 1Electricity-source of energy produced by flow or storage of electrons (sub- atomic particles with negative charge)
- 2Electronic Deviceprocess electricity for various functions (amplify electrical signal, perform calculations, store binary info)
- 3Atoms(what all matter is composed of)- composed of protons (+), neutrons (no charge), electrons (-).
- 4protons and neutrons-tightly bond at the core (atom nucleus)
- 5electrons-orbit around the core
- 6Force (F) between electrical chargesDirectly proportional to charge
Inversely proportional to the distance between charges - 7Element-an atom that cannot be subdivided into smaller substances
- 8Atomic number=number of Protons
- 9Compounds-when two or more elements combine to form a new substance.
- 10Molecule-smallest form of a compound, exhibits properties of the substance
- 11Conductorsallow current flow): Silver (best), Copper (2nd best)
- 12Insulators (poor conductors):Glass, Porcelain, Teflon
- 13Voltage:establishes electrical current; amount of energy available to move electrons from one point to another in a circuit; measured in Volts (V); i.e. batteries, solar cells, generators; (negative to positive when applied to conductive or semiconductive material & random motion of free electrons)
- 14Current (I):time rate of electron (charge) flow; measured in ampere (A).
- 15Resistance:opposition to current; materials tend to resist flow of electricity through them (resistance); measured in ohms
- 16Digital Multimeter (DMM)-measures voltage, current, and resistance
- 17Joule-work done when a force of one newton is applied through one meter
