Term | Definition | Example Sentence |
---|---|---|

Breadboard | A circuit board for wiring temporary circuits, usually used for prototypes or laboratory work. | |

Conventional Current | The direction of current flow associated with positive charge in motion. The current flow direction is from a positive to negative potential, which is in the opposite direction of electron flow. | |

Current | A movement of electrical charges around a closed path or circuit. | |

Digital | A way of representing a physical quantity by a series of binary numbers. A digital representation can have only specific discrete values. | |

Digital Multi-Meter (DMM) | A piece of test equipment used to measure voltage, current, and resistance in an electronic circuit. | |

Engineering Notation | A floating point system in which numbers are expressed as products consisting of a number greater than one multiplied by an appropriate power of ten that is some multiple of three. | |

Kirchhoff's Current Law (KCL) | The algebraic sum of all currents into and out of any branch point in a circuit must equal zero. | |

Kirchhoff's Voltage Law (KVL) | The algebraic sum of all voltages around any closed path must equal zero. | |

LED | Light-emitting diode. An electronic device that conducts current in one direction only and illuminates when it is conducting. | |

Ohm | Unit of resistance. Value of one ohm allow current of one ampere with potential difference of one volt. | |

Ohm's Law | In electric circuits, I=V/R. | |

Parallel Circuit | One that has two or more branches for separate current from one voltage source. | |

Resistance | Opposition to current. Unit is the ohm. | |

Resistor Color Code | Coding system of colored stripes on a resistor to indicate the resistor's value and tolerance. | |

Scientific Notation | Numbers entered as a number from one to ten multiplied by a power of ten. | |

Series Circuit | One that has only one path current. | |

SI Notation | Abbreviation of System International, a system of practical units based on the meter, kilogram, second, ampere, Kelvin, mole, and candela. | |

Solder | Metallic alloy of tin and lead that is used to join two metal surfaces. | |

Soldering | Process of joining two metallic surfaces to make an electrical contact by melting solder (usually tin and lead) across them. | |

Soldering Iron | Tool with an internal heating element used to heat surfaces being soldered to the point where the solder becomes molten. | |

Analog | A way of representing some physical quantity, such as temperature or velocity, by a proportional continuous voltage or current. An analog voltage or current can have any value within a defined range. | The clock is 'analog' because the time is constantly changing and is continuous (different time each time you look). |
