# Lesson 1.1 Intro

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

Breadboard | A circuit board for wiring temporary circuits, usually used for prototypes or laboratory work. | I am not done with my breadboard so I lock it under the table. |

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. | My light bulb current has a conventional current. |

Current | A movement of electrical charges around a closed path or circuit. | I didn't know if a circuit my partner was working on had a current so I unplugged the power source. |

Digital | A way of representing a physical quantity by a series of binary numbers. A digital representation can have only specific discrete values. | My clock is easy to read because it is digital. |

Digital Multi-Meter(DMM) | A piece of test equipment used to measure voltage, current, and resistance in an electronic circuit. | I always keep a DMM in case I need to measure my circuit. |

Resistor color code | Coding system of colored stripes on a resistor to indicate the resistor's value and tolerance. | I needed to find out which resistor I was using so I checked the resistor color code. |

Scientific Notation | Numbers entered as a number from one to ten multiplied by a power of ten. | Scientific Notation makes it easier to write large numbers. |

Solder | Metallic alloy of tin and lead that is used to join two metal surfaces. | I used a solder to wire two wires together. |

Soldering | Process of joining two metallic surfaces to make an electrical contact by melting solder (usually tin and lead) across them. | While Soldering my wires, I made sure to wear my goggles. |

Soldering Iron | Tool with an internal heating element used to heat surfaces being soldered to the point where the solder becomes molten. | The soldering iron was very hot but I did not touch it. |

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. | Engineering Notation is similar to Scientific notation but it has exponents. |

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 measure if the current in my circuit equals up. |

Kirchhoff’s Voltage Law (KVL) | The algebraic sum of all voltages around any closed path must equal zero. | I used KVL to measure the voltage of my parallel circuit. |

LED | Light-emitting diode. An electronic device that conducts current in one direction only and illuminates when it is conducting. | My Christmas tree lost one of its LEDs. |

Ohm | Unit of resistance. Value of one ohm allow current of one ampere with potential difference of one volt. | I needed to measure the number of Ohms in my circuit. |

Ohm's law | In electric circuits, I=V/R. | I did not know the resistance of my circuit so I used Ohm's law to calculate it. |

Parallel Circuit | One that has two or more branches for separate current from one voltage source. | My house has parallel circuits. |

Resistance | One that has two or more branches for separate current from one voltage source. | The resistance in my circuit is very strong so I change it to a different resistor. |

Series Circuit | One that has only one path current. | I built a series circuit to power a small light bulb. |

Simulation | Testing design function by specifying a set of inputs and observing the resultant outputs. Simulation is generally shown as a series of input and output waveforms. | I used a roller coaster simulation to cure my fear of roller coasters. |

SI Notation | Abbreviation of System International, a system of practical units based on the meter, kilogram, second, ampere, Kelvin, mole, and candela. | The system that is not preferred in America and Liberia. |

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 clock in my room is an analog clock. |
