Circuits
| Term | Definition |
|---|---|
| schematic | circuit diagram |
| open circuit | the closed conducting loop is broken and no charge flows |
| closed circuit | the closed conducting loop allows charge to flow |
| short circuit | nothing slows down current because there is a direct path back to the battery (no resistance); can cause overheating, melting, etc. |
| current | how many charges pass through a cross-section of wire in a certain amount of time |
| conventional current | the idea that current flows from the positive side of a battery to the negative side |
| electron flow | the idea that current flows from the negative side of a battery to the positive side (also called real current) |
| Coulomb | the unit for charge; the amount of charge transported by a steady current of one amp in one second |
| filament | the wire inside of a light bulb's globe that glows |
| globe | the glass casing on the outside of a light bulb filled with gas |
| ribbed edge | the metal portion of the light bulb that screws into a fixture or light bulb holder |
| base | the conducting part at the very bottom of a light bulb |
| insulating material | strip of material at the bottom of the light bulb that separates the ribbed edge from the base |
| cathode | the positive terminal or electrode of a battery |
| anode | the negative terminal or electrode of a battery |
| separator | the barrier between the cathode and anode of a battery |
| electrolyte solution | allows electrons to flow from the cathode to the anode inside of the battery |
| volts | the unit for a battery's potential energy, or voltage |
| voltage | a battery's potential energy |
| resistance | property of a material to restrict the flow of charges |
