### Introduction to Electronics

Term | Definition |
---|---|

Analog | Representation of physical quantities by proportional continuous current or voltage. - Temperature - Velocity |

Breadboard | Temporary wiring circuit board. |

Conventional Current | Current flow form positive to negative potential, opposite of electron flow. |

Current | The movement of voltage through a circuit. |

Digital | Representation of physical quantities by binary on and off signals. Only has specified discrete values. |

Digital Multi-Meter(DMM) | Tool used to measure voltage, current and resistance in a circuit. |

Engineering Notation | The engineering equivalent of scientific notation but the power of ten is a multiple of 3. |

Kirchhoff’s Current Law (KCL) | The sum of all currents in and out of a branch point must be zero. |

Kirchhoff’s Voltage Law (KVL) | The sum of all voltages around a closed path , must be zero. |

LED | One-directional current editor used for illumination when conducted, called a light-emitting diode. |

Ohm | Omega, unit of resistance equal to one ampere with a voltage of one. |

Ohm’s Law | Current is equal to Voltage over Resistance. I = V/R |

Parallel Circuit | A circuit with one or more branches with independent current coming from a single voltage source/ |

Resistance | Opposition to current measured in ohm's. |

Resistor Color Code | Color code found on resistors classifying resistor value and tolerance/offset from that value. |

Scientific Notation | Notation where in numbers are classified with a number multiplied by ten to some power. - 2000 becomes 2 x 10^3 |

Series Circuit | Circuit with only one current path. |

Simulation | Testing done through the observation of input and output waveforms with data given from system the system is getting the simulation done for. |

SI Notation | A system of units used around the world. - Kilometer, Kelvin, Mole |

Solder | Metallic alloy that is melted onto two metal surfaces for joining. |

Soldering | Joining two metal surfaces through the use of a soldering iron and applying solder onto to the place in question. |

Soldering Iron | Tool that heats solder material and melts it for application onto metallic surfaces. |
