Unit 6 & 7
UNITS 6 & 7 VOCAB DEFINITIONS #2
| Term | Definition |
|---|---|
| Electromagnets | magnets that carry an electrical current; can be made stronger & turned on & off. |
| Hazard | something that is dangerous and may result in being harmful. |
| Cause | an action, reason, or event that takes places. |
| Effect | the result or consequences of the action (cause). |
| Parallel / Complex circuit | a circuit that has more than one branch or pathway for electrons to flow through and more than one resistor- light bulb, buzzer, bell, fan, etc. If one goes out the others stay on. This is what homes, buildings, businesses have. |
| Ohm | a unit that measure resistance to electrical current. |
| Volt | a measure of the electrical force provided by an energy source. |
| Circuit | a loop/pathway for the electric charges to flow. |
| Series circuit | a circuit that has more than one resistor on the same wire- 1 pathway. |
| Current | the flow of electrical charges (electrons) through a material. |
| Conductor | a material that an electrical charge can move easily through- metals- gold, silver, nails, aluminum, iron, bronze, mercury(liquid), copper. |
| Insulator | a material that is a resistor and stops most electrical currents- paper, plastic, rubber, glass, quartz, dry wood, air, ceramics. |
| Resistor | a material that does not let all the electrical charge flow and changes some of the electrical energy to thermal energy; limits the amount of current flowing through. Represented by a zig-zag line on the circuit. Made of glass, wire, film |
| Electricity | the flow of electrons (e-) through a material. |
| Circuit diagram | a map of a circuit. |
| Simple Circuit | a circuit that has only one pathway for electricity to flow through & 1 resistor. |
| Overloaded Circuit | a circuit that has too many resistors working at one time. |
| Advantage/ beneficial | something that is good or helpful. |
| Disadvantage/ Drawback | something that is bad or not helpful. |
| Proton | positively-charged subatomic particle in the nucleus of the atom. |
| Neutron | neutral/ no charge subatomic particle in the nucleus of the atom. |
| Electron | negatively-charged subatomic particle outside the nucleus in shells, orbitals, or cloud. |
| Superconductors | materials that have no resistance to electrical charges; let all electrons flow through and operate at very cold temperatures. |
| Filament | the thin wire inside a light bulb that is part of the circuit; conducts heat & electric current. |
