TermDefinition
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.
