TermDefinitionExamples
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 electric 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.
Kirchhoff's Current Law (KCL) The algebraic sum of all current into and out of any branch point in a circuit must equal zero.
Kirchhoff'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's Unit of resistance. Value of one ohm allow current of one ampere with potential difference of one volt.
Parallel Circuit In electric circuits, l=V/R.
Resistance One that has two or more branches for separate current from one voltage source.
Resistor Color Code Opposition to current. Unit is the ohm.
Scientific Notation Coding system of colored stripes in a resistor to indicate the resistor’s value and tolerance.
Series Circuit One that has only one path current.
SI Notation Abbreviation of system international’ a system of practical units based on the meter, kilogram, second, ampere, kelvin, mole, and candela.
Solder Metallic alloy of tin and lead that to join two metal surface.
Soldering Processing of joining two metal surface to make an electronical contact by melting solder (usually tin and lead) across them.
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 of representing some physical quantity, such as temperature or velocity, by a proportional continuous voltage or current. Analog voltage or current can have any value within a defined range
