Term | Definition | Example sentence |
---|---|---|

Breadboard | A circuit board for wiring temporary circuits, usually used for prototypes or laboratory work. | We will be using breadboards soon in digital electronics class to program prototypes to se if they work. |

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. | A battery uses some type of conventional circuit since it is moving from positive side to negative side. |

Current | A movement of electrical charges around a closed path or circuit. | The current is passing from pole line to pole line to get power. |

Digital | A way of representing a physical quantity by a series of binary numbers. A digital representation can only have only specific discrete values. | My phone is powered and since it is digital it has all the power in one hand-holding device. |

Digital Multi-Meter(DMM) | A piece of test equipment used to measure voltage, current, and resistance in an electronic values | I need a digital multi-meter so I can see how much volts this battery has. |

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. | I would need an engineering notation so that I would be able to figure out the solution. |

Kirchoff's Current Law (KCL) | The algebraic sum of all currents into and out of any branch point in a circuit must equal zero. | I know that the output of a circuit not mattering where will always zero because of the kirchoff's current law. |

Kirchoff's Voltage Law(KVL) | The algebraic sum of all voltages around any closed path must equal zero. | The kirchoff's voltage law allows me to put in a voltage and get an output result of zero. |

LED | Light-emitting diode. An electronic device that conducts current in one direction only and illuminates when it is conducting. | The LED turned on when the robot detected it was dark. |

Ohm | Unit of resistance. Value of one ohm allow current of one ampere with potential difference of one volt. | There are 30 ohms inside this toy while it is functioning. |

Ohm's Law | In electric circuits, I=V/R | If I use I=V/R then I can find how many ohms there are. |

Parallel Circuit | One that has two or more branches for separate current from one voltage source | I need to use a parallel circuit if I want to have two different currents of voltage at the same time. |

Resistance | Opposition to current. Unit is the ohm. | Resistance is what I need to see how much I power I can put in. |

Resistor Color code | Coding system of colored stripes on a resistance to indicate the resistor's value and tolerance. | If I have the Resistor Color Code I can find out how much I need to make this circuit work. |

Scientific Notation | Numbers entered as a number from one to ten multiplied by a power of ten. | The scientific notation helps me figure out the amount of power I need for this processor. |

Series Circuit | One that has only path current. | Series Circuit act like train tracks which they follow one track. |

SI Notation | Abbreviation of System International, a system of practical units based on the meter, kilogram, second, ampere, Kelvin, mole, and candela. | The SI notation helped me figure out what kind of power a light bulb produced. |

Solder | Metallic alloy of tin and lead that is used to join two metal surfaces. | I solder a pole to another so that I could make a barrier between me and my friend. |

Soldering | Process of joining two metallic surfaces to make an electric contact by melting solder(usually tin and lead) across them. | I am soldering so that I can make something to hold up these roofs. |

Soldering iron | Tool with an internal heating element used to heat surfaces being soldered to the point where the solder become molten. | The soldering iron helps me burn them so that they can become one. |

Analog | A way of representing some physically 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 analog uses more of frequent waves to connect. |
