### Engineering

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

Breadboard | A circuit board for wiring temporary circuits, usually used for prototypes or laboratory work. | We need to connect the LED and resistors to the breadboard |

Conventional Circuit | 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. | Conventional Circuits and Electron Flows have many differences |

Current | A movement of electrical charges around a closed path or circuit | The current flowing through this circuit is dangerously high |

Digital | A way of representing a physical quantity by a series of binary numbers. A digital representation can have only specific discrete values. | The clock on my phone is "digital" |

Digital Multi-Meter (DMM) | A piece of test equipment used to measure voltage, current, and resistance in an electronic circuit. | We use the digital multi-meter to make sure there are no dangerous currents flowing |

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 | Writing in Engineering Notation makes it faster and shorter to write large/small numbers that contains lots of zero's |

Kirchhoff's Current Law (KCL) | The algebraic sum of all currents into and out of any branch point in a circuit must equal zero. | Using Kirchhoff's current law, I now know that all the currents are the same in a Parallel Circuit |

Kirchhoff's Voltage Law (KVL) | The algebraic sum of all voltages around any closed path must equal zero. | Using Kirchhoff's Voltage Law, I now know that all the voltages in a series circuit are the same |

LED | Light-emitting diode. An electronic device tat conducts current in one direction only and illuminates when it is conducting | This Christmas tree has LED lights to make the tree look colorful |

Ohm | Unit of resistance. Value of one ohm allow current of one ampere with potential difference of one volt. | This light bulb contains 4 ohms |

Ohm's Law | In electric circuits, I=V/R | Ohm's Law is used to help solve for missing information in circuits |

Parallel Circuit | One that has two or more branches for separate current from one voltage source | Usually hallway lights use parallel circuits to make sure they are all powered evenly throughout the hallways |

Resistance | Opposition to current. Unit is the Ohm | This light bulb has a very high resistance |

Resistance Color Code | Coding system of colored stripes on a resistor to indicate the resistor's value and tolerance | This resistor has green first and red next as the Resistance color code |

Scientific Notation | Numbers entered as a number from one to ten multiplied by a power of ten | When we are talking about large/ really small numbers, we would use scientific notation to shorten the length of the number written |

Series Circuit | One that has only one path current | A series circuit is sometimes used in Christmas tree lights |

SI Notation | Abbreviation of System International, a system of practical units based on the meter, kilogram, second, ampere, Kelvin, mole, and candela | Our teacher wants us to make sure we put all of our answers in with SI notation |

Solder | Metallic alloy of tin and lead that is used to join two metal surfaces | The resistor is coming off the motherboard. I need to solder it to get the connection working again |

Soldering | Process of joining two metallic surfaces to make an electrical contact by melting solder (usually tin and lead) across them | Soldering takes time and practice to get right. It is a slow process and must be done carefully |

Soldering Iron | Tool with an internal heating element used to heat surfaces being soldered to the point where the solder becomes molten | I need to use the soldering iron to connect the resistor to the motherboard |

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 school clock on the walls are "analog" |
