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

Breadboard | A circuit board for wiring temporary circuits, usually used for prototypes or laboratory | I connected wires to the bread board |

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 | The electrons in conventional current flow in the same direction |

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 | Many old radios use analog |

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

Digital multi-meter(DMM) | A piece of test equipment used to measure voltage, current, and resistance in an electronic circuit | I used the multi-meter to measure the resistance of my 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 | I used engineering notation of calculations |

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 used (KCL) to solve for the missing current |

Kirchhoff's Voltage Law (KVL) | The algebraic sum of all voltages around any closed path must equal zero | I used (KVL) to solve for missing voltage |

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

Ohm | Unit of resistance. Value of one ohm allow current of one ampere with potential difference of one volt | The multi-meter read 3 Ohms |

Ohm's Law | In electrical circuits, I=V/R | I used Ohm's law to calculate the current |

Parallel Circuit | One that has two or more branches for separate current from one voltage source | The lights in the school are arranged in a parallel circuit |

Resistance | Opposition to current. Unit is the Ohm | I used to multi-meter to measure the resistance |

Resistor Color Code | Coding system of colored stripes on a resistor to indicate the resistor's value and tolerance | The resistor color code indicated that it had high resistance |

Scientific Notation | Numbers entered as a number from one to ten multiplied by a power of ten | i used scientific notation to write 10 to the power 6 |

Series Circuit | One that has only one path current | i made a simple circuit in a series |

SI Notation | Abbreviation of system international, a system of practical units based on the meter, kilogram, second, ampere, kelvin, mole, and candela | i used si notation to write the current temperature of the room |

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

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

Current | A movement of electrical charges around a closed path or circuit | I got shocked by the "current" when i touched the exposed wires |
