Term | Definition | Ex. Sentence |
---|---|---|

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 Analog button for my thermostat was set low. |

Breadboard | A circuit board for wiring temporary circuits, usually used for prototypes or laboratory work. | My breadboard was overheated to the point it burned out. I had to get a new one. |

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 electrical flow. | My convential current from my xbox powercord was a strong charge. |

Digital | A way of representing a physical quantity by a series of binary numbers. A digital representation can have only specific discrete values. | My Digital camera has very good quality. |

Digital Multi-Meter (DMM) | A piece of test equipment used to measure voltage, current, and resistance in an electronic circuit. | The schools digital multi meter has gone missing because the students do not take care of them. |

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 | An engineering notation problem was used on the daily quiz. |

Kirchhoff's current Law (KCL) | The algebraic sum of all currents into and out of any branch point in a circuit must equal zero. | I got Kirchhoff's current law while trying to take my test. |

Kirchhoff's Voltage law | The algebraic sum of all voltages around any closed path must equal zero | Kirchhoff's voltage law needed to be used in finding the circuit. |

LED | Light-emitting diode. An electronic device that conducts current in one direction only and illuminates when it is conduction. | I installed LED lights in my room to set the mood. |

Ohm | Unit of resistance. Value of one ohm allow current of one ampere with potential difference of one volt. | Ohm in 1827, and since known as Ohm's Law. |

Ohm's Law | In Electric Circuits, I=V/R | Ohm's Law was used to solve my homework problem today. |

Parallel Circuit | One that has two or more branches for separate current from one voltage source. | I made a parallel circuit drawing today apart of my warmup. |

Resistance | Opposition to current. Unit is the ohm. | The resistance between on side of the rope was very weak. |

Resistor Color Code | Coding system of colored stripes on a resistor to indicate the resistor's value and tolerance. | The resistor's Color code was very rgb like. |

Scientific Notation | Numbers entered as a number from one to ten multiplied by a power of ten. | The scientific notation for 4 was used in our test today. |
