| Term | Definition |
|---|---|
| Bread Board | A circuit board for wiring temporary circuits, usually for prototypes or Lab work |
| 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 a electron. |
| Current | A movement of electrical charges around a closed path or circuit |
| Digital | A way of representing a physical quantity by a series of binary numbers. A digital representation can have only specific discrete values |
| Digital Multi meter (DMM) | A piece of test equipment used to measure voltage, current, and resistance in and electronic 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 |
| Kirchhoff's Current Law (KCL) | he algebraic sum of all currents into and out of any branch point in circuit must equal zero |
| Kirchhoff's voltage law (KVL) | The algebraic sum of all currents into and out of any branch point in a circuit must equal zero |
| LED | Light-emitting diode and electronic device that conducts current in one direction only and illuminates when is conducting |
| ohm | Unit of resistance. value of one ohm allow current of one ampere with potential difference of one volt. |
| Ohms law | In electric circuits, I=v/r. |
| Parallel circuit | one that has two or more branches for separate current form one voltage source |
| Resistance | Opposition to current. Unit os the ohm |
| Resistor color code | Coding system of colored stripes on a resistor to indicate resistor value and tolerance |
| Scientific notation | Numbers entered as a number from one tot ten multiplied by a power of ten |
| Series Circuit | one that has only one path current |
| SI Notation | Abbreviation of system international, a system practical units based on the meter, kilogram second, ampere, kelvin, mole, and candela |
| Solder | Metallic alloy of tin and elad that is used to join two metal surfaces |
| Soldering | Process of joining two metallic surfaces to make an electrical contact by melting surfaces together |
| Soldering Iron | Tool with an internal heating element used to heat surfaces being soldered to the point where the solder becomes molten |
| Analog | A way representing some physical quantity such as temperature or velocity by a proportional continuous voltage or current. An analog voltage or current can have any values within a defined range. |
