Unit 1.1 Part A.
| Term | Definition |
|---|---|
| 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. |
| Breadboard | A circuit board for wiring temporary circuits, usually used for prototypes or laboratory 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 electron flow. |
| 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 an 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. |
| Kirchoff's Current Law (KCL) | The algebraic sum of all currents into and out of any branch point in a circuit must equal zero. |
| Kirchoff's Voltage Law (KVL) | The algebraic sum of all voltages around any closed path must equal zero. |
| LED | Light-emitting diode. An electronic device that conducts current in one direction only and illuminates when it is conducting. |
| Ohm | Unit of resistance. Value of one ohm allow current of one ampere with potential difference of one volt. |
| Ohm's law | In electric circuits, I=V/R. |
| Parallel Circuit | One that has two or more branches for separate current from one voltage source. |
| 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. |
| Scientific Notation | Numbers entered as a number from on eta ten multiplied by a power of ten. |
| Series Circuit | One that has only one path current. |
| SI Notation | Abbreviation of System International, a system of practical units based of the meter, kilogram, second, ampere, Kelvin, mole, and candela. |
| Solder | Metallic alloy of tin and lead that is used to join two metal surfaces. |
| Soldering | Process of joining two metallic surfaces. to make and electrical contact by melting solder across them. |
| Soldering Iron | Tool with an internal heating element used to heat surfaces being soldered to the point where the solder becomes molten. |
