TermDefinitionExample Sentence
Breadboard A circuit board for wiring temporary circuits, usually used for prototypes or laboratory I connected wires to the bread board
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 The electrons in conventional current flow in the same direction
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 Many old radios use analog
Digital A way of representing a physical quantity by a series of binary numbers. A digital representing can have only specific discrete values. My phone uses digital coding
Digital multi-meter(DMM) A piece of test equipment used to measure voltage, current, and resistance in an electronic circuit I used the multi-meter to measure the resistance of 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 I used engineering notation of calculations
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 solve for the missing current
Kirchhoff's Voltage Law (KVL) The algebraic sum of all voltages around any closed path must equal zero I used (KVL) to solve for missing voltage
LED Light-emitting diode. An electronic device that conducts current in one direction only and only illuminates when it is conducting The LED display in my phone is broken
Ohm Unit of resistance. Value of one ohm allow current of one ampere with potential difference of one volt The multi-meter read 3 Ohms
Ohm's Law In electrical circuits, I=V/R I used Ohm's law to calculate the current
Parallel Circuit One that has two or more branches for separate current from one voltage source The lights in the school are arranged in a parallel circuit
Resistance Opposition to current. Unit is the Ohm I used to multi-meter to measure the resistance
Resistor Color Code Coding system of colored stripes on a resistor to indicate the resistor's value and tolerance The resistor color code indicated that it had high resistance
Scientific Notation Numbers entered as a number from one to ten multiplied by a power of ten i used scientific notation to write 10 to the power 6
Series Circuit One that has only one path current i made a simple circuit in a series
SI Notation Abbreviation of system international, a system of practical units based on the meter, kilogram, second, ampere, kelvin, mole, and candela i used si notation to write the current temperature of the room
Soldering Process of joining two metallic surfaces to make an electrical contact by melting solder (usually tin and lead) across them. i used soldering to connect my circuit
Soldering Iron Tool with an internal heating element used to heat surfaces being soldered to the point where the solder becomes molten. i use the soldering iron to solder
Current A movement of electrical charges around a closed path or circuit I got shocked by the "current" when i touched the exposed wires
