Current | A movement of electrical charges around a closed path or circuit. | The current flow from positive to negative. |

Digital | A way of representing a physical quantity by a series of binary number. A digital representation can have only specific | In digital circuits 5v mean 1 and 0v means 0 |

Engineering Notation | A floating Point system in which numbers are expressed as product consisting of a number greater than one multiplied by an appropriate power of ten that is some multiple of three | |

Kirchoff's Current Law (KCL) | The algebraic sum of all currents into and out of any branch point in a circuit must equal zero | Kirchhoff's Current Law is use to resolve electronic circuit to let us know the intensity of the current |

Kirchhoff's Voltage Law (KVL) | The algebraic sum of all voltages around any closed path must equal zero | Kirchhoff's Voltage Law can help us know the amount of volts in each eclectic derives in a closed circuit |

LED | Light-emitting diode, An electronic device that conduct current in one direction only and illuminates when it is conducting | LED's can only work in a DC |

Ohm | Unit of resistance. Value of one ohm allow current of one ampere with potential differce of one volt | |

Ohm's Law | In electric circuits, I=V/R | Ohm's law is the basis of the electricity |

Parallel Circuit | One that has two or more branches for separate current from one voltage source | Parallel circuit shared the same voltage |

Resistance | Opposition to current unit is the ohm | |

Resistor Color Code | Coding system of colored stripes on a resistor to indicate the resistor's value and tolerance | Resistor color code helps us to identified the value of the resistance. |

Scientific Notation | Number entered as a number from one to ten multiplied by a power of ten | Scientific notation is used to represent a large number in that compacted number |

Series Circuit | One that has only one path current | Series circuit share the same amount of current |

SI Notation | Abbreviation of System International, a system of practical units based on the meter, Kilogram , second, ampere, kelvin, mole, and candela. | SI notation is the most used system of units |

Solder | Metallic alloy of tin and lead that is used to join two metal surface | Solder help us unite two electronic devises |

Soldering | Process of joining two metallic surfaces to make an electrical contact | |

Soldering Iron | Tool with an internal heating element used to heat surfaces being soldered to the point where the solder becomes molten | Soldering iron uses iron in a high current to melt metals |

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 dined range | Analog is a system of measurement the represents a change of physical values |
