FOSS 8 Elect Vocab
FOSS 8 Electronics Vocabulary
| Question | Answer |
|---|---|
| Alternating Current (AC) | The flow of electricity goes both ways. |
| Ammeter | The tool used to measure electric current. Unit of measure is amps (A) or milliamps (mA). |
| Amps (A) | The unit of measure for electric current. Used in Ohm’s Law. |
| Artistic Drawing | A drawing of a circuit that looks like the actual circuit and does not use schematic symbols. |
| Atom | The smallest part of matter that can exist on its own. |
| Atom | Tiny particles that make up all matter. |
| Capacitor | A component made of two metal plates separated by an insulator that can store electric potential |
| Capacitor | A charge/discharge device. |
| Circuit | The pathway electricity travels through. |
| Closed Circuit | A complete (unbroken) pathway where electricity flows to all components |
| Component | Part of a circuit (bulb, switch, wire, battery, etc.) |
| Conductor | Material that allows electricity / current to flow through. |
| Current (1) | The flow of electricity / electrons. Can be positive (+) or negative (-). |
| Current (2) | The number of electrons (amount of charge) flowing past a specified point within a given period of time. Measured in amps (A) or milliamps (mA). |
| Data | Measurable results of an experiment. |
| Diode | A component that only conducts current in one direction. A solid-state semi-conductor. |
| Direct Current (DC) | The flow of electricity is only one direction. |
| Direct Relationship | A mathematical relationship in which both variables increase or decrease together. In a playground analogy, direct relationship is like a slide. |
| Electricity | The movement or flow of electrons. |
| Electron | A negatively charged particle that orbits the nucleus of an atom. |
| Hypothesis | An educated guess or prediction based on background knowledge. This prediction can be tested. |
| Inference | A logical conclusion based on given information and background knowledge but not specifically stated. |
| Insulator | Material that does not allow electricity / current to flow through. |
| Inverse Relationship | A mathematical relationship between two variables where as one value increases the other decreases. In a playground analogy, an inverse relationship is like a teeter-totter. |
| LED | A solid-state semiconductor that gives off light |
| Light Emitting Diode | LED. A solid state semiconductor that gives off light. |
| Milliamps (mA) | The unit of measure for electric current as read by the ammeter. |
| Neutron | A neutral particle (no charge) in the nucleus of an atom. |
| Observation | What we see, hear, feel, taste, smell. The way we describe an object or an event. |
| Ohm | A unit of measure for resistance |
| Ohmmeter | A tool used to measure resistance (ohms). Can be found on a multimeter. |
| Open Circuit | An incomplete (broken) pathway where electricity flows only to some of the components. |
| Parallel Circuit | A circuit where some components are on their own pathway. A device can contain both series and parallel circuits. |
| Potentiometer | A variable resistor that can change the amount of resistance in a circuit. |
| Proton | A positively charged particle in the nucleus of an atom. |
| Qualitative Observation | An observation that describes something but cannot be measured (color, feel, smell, what it looks like) |
| Quantitative Observation | An observation that can be measured (length, height, mass, temperature) |
| Question | Something you want to find out. |
| Resistance | The property of materials that resists the flow of electricity. |
| Resistor | A component found in an electronic circuit that is used to reduce or stop the flow of electricity. |
| Schematic | A drawing of a circuit that uses standard symbols to represent the components and design of a circuit. |
| Semiconductor | A material that sometimes acts as an insulator and sometimes acts as a conductor. |
| Series Circuit | A circuit where all components are on one pathway (in a line). |
| Short Circuit | A pathway that allows current to bypass a component in the circuit. This only happens in a parallel circuit. |
| Threshold Voltage | The minimum amount of voltage at which some components conduct electricity. |
| Transistor | A semiconductor component that acts like both an amplifier and a switch. It contains elements of both a diode and a capacitor. |
| Voltage | The amount of force or push in a circuit that moves the electrons through the circuit. |
| Voltage Drop | How much voltage (electricity) is used by each component in a circuit |
| Voltmeter | A tool that measures voltage (v). Can be found on a multimeter. |
