---|---|---|

Breadboard | A circuit board for writing temporary circuit, usually used for prototype or laboratory work | We us bread boards to test experimental electronic circuits |

Conventional current | The direction of the current flow associated with positive charge in motion. The current flow direction is from a positive and negative potential ,which is in the opposite direction of electron flow | A microwave uses conventional current |

Current | A movement of electrical charges around a closed path or circuit | The current of the water was strong and fast |

Digital | A way of representing a physical quantity by a series of binary numbers.A digital representation can have only specific discrete value | My teacher showed me digital number of how many dogs there were on the screen |

Digital Multi -Meter | A piece of test equipment uses to measure voltage ,current, and resistance in an electronic circuit. | We didn’t know the valtage so me and my friends used the multi- meter |

Engineering notation | A floating system in which number are expressed as products consisting of numbers greater than one multiplied by an appropriate power of ten that is some multiple of three | Engineers use engineering nations to complete work |

Kirchhoff current Law(KCL) | The algebraic sum of all current into and out any branch point in a circuit must equal zero | Kirchhoff’ current Law |

Kirchhoff's voltage Law(KVL) | The algebraic sum of all voltages around any closed path must equal zero | Kirchhoff’s voltage Law makes sure every closed path equals zero |

LED | Lighting- emitting diode.AN electronic device that conducts current in one direction only and illuminates when it conducting | I put LED lights around my room |

ohms | Unit of resistance. Value of one ohms allows current of one emperor with potential difference of one volt | it takes a certain amount of ohms to power up the flash light |

Ohms law | In electric circuits, I equals V/R | ohms law requires Voltage and resistance |

Parallel circuit | One that has two or more branches for separate current from one voltage source | i have parallel circuit running in my room |

Resistance | Opposition to current. Unit is the ohms | Over time the patient could develop a resistance to the drug. |

Resistor color code | Coding system of colored stripes on a resistor to indicate there is a resistors value of tolerance | We used resistor color code in our class to figure out the resistance tolerance |

Scientific notation | Numbers entered as a number from 1 to 10 multiplied by power of 10 | We multiplied 4 muiltiplied but the power of ten is called scientific notion |

Series circuitS I space notation | one that has only one path current | A parallel circuit is an example of a series circuit si space notation |

SI notation | Abbreviation of a system international, a system of practical units based on the meter, kilograms, second, and prayer, Calvin, mole, and candela | The metric system uses si notion |

Solder | Metallic alloy of tin that is used to join two metal surface | i solder two metallic alloys tin my metal board |

soldering | Process of joining tomb metallic surface to make an electrical contact by melting sholder(usually tin and lead)aross them | me and my friends were soldering in our engineering class |

Soldiering iron | Tool with an internal heating element used to heat surfaces being soldered to the point where the solder becomes molten | We used the soldering iron to combine town metals |

Analog | A way of representing some physical quantity, such as temperature or velocity, by a proportional continuous voltage or current can have any value within a defined range. | The analog on my computer was super fast |
