Term | Definition | Example Sentence |
---|---|---|
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. | "Almost every 'analog' clock has the red second hand." |
Breadboard | A circuit board for wiring temporary circuits, usually used for prototypes or laboratory work. | "The 'breadboard' is sometimes the building block for circuits." |
Conventional Current | The direction of current flow associated with positive chare in motion. The current flow direction is from positive to negative potential, which is in the opposite direction of electron flow. | "Some circuits could have a 'conventional current' type flow." |
Current | A movement of electrical charges around a closed path or circuit. | "I managed to get the 'current' to flow by closing the circuit." |
Digital | A way of representing a physical quantity by a series of binary numbers. A digital representation can have only specific discrete values. | "A 'digital' clock only updates the time every minute." |
Digital Multi-Meter (DMM) | A piece of test equipment used to measure voltage, current, and resistance in an electronic circuit. | "I used the 'digital multi-meter' to measure the voltage in my 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. | "Some of my engineering answers are in 'engineering notation' form." |
Kirchhoff's Current Law (KCL) | The algebraic sum of all currents into and out of any branch point in a circuit must equal zero. | "The way 'Kirchhoff's Current Law' is stated is that current stays the same in any circuit." |
Kirchhoff's Voltage Law (KVL) | The algebraic sum of all voltages around any closed path must equal zero. | "The way 'Kirchhoff's Voltage Law' is stated is that voltage stays the same in any circuit." |
LED | Light-emitting diode. An electronic device that conducts current in one direction only and illuminates when it is conducting. | "Many lights are 'LED' lights." |
Ohm | Unit of resistance. Value of one ohm allow current of one ampere with potential difference of one volt. | "My resistor measures 1 'Ohm'." |
Ohm's Law | In electric circuits, I=V/R. | "Some of my calculations require the 'Ohm's Law' formula." |
Parallel Circuit | One that has two or more branches for separate current from one voltage source. | "My classroom lights are a visual representation of a "Parallel Circuit'." |
Resistance | Opposition to current. Unit is the Ohm. | "My resistors measure 'resistance' in ohms." |
Resistor Color Code | Coding system of colored stripes on a resistor to indicate the resistor's value and tolerance. | "I took down notes of the 'Resistor Color Code' for my resistors." |
Scientific Notation | Numbers entered as a number from one to ten multiplied by a power of ten. | "Another batch of my answers are in 'Scientific Notation'." |
Series Circuit | One that has only one path current. | "This circuit I am working on is a 'series circuit'." |
SI Notation | Abbreviation of System International, a system of practical units based on the meter, kilogram, second, ampere, Kelvin, mole, and candela. | "Many countries use the 'SI Notation'." |
Solder | Metallic alloy of tin and lead that is used to join two metal surfaces. | "I am holding a piece of 'solder'." |
Soldering | Process of joining two metallic surfaces to make an electrical contact by melting solder (usually tin or lead) across them. | "I am 'soldering' my solder." |
Soldering Iron | Tool with an internal heating element used to heat surfaces being soldered to the point where the solder becomes molten. | "I am using a 'Soldering Iron' to help with the soldering." |
