Lesson 1.1

TermDefinition
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. *My clock is analog because it's continuous (seconds)
Breadboard A circuit board for wiring temporary circuits, usually used for prototypes or laboratory work. *A breadboard would be ideal for the trial and error process
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 *The current is can't flow because there is a gap
Digital A way of representing a physical quantity by a series of binary numbers. A digital representation can only have specific discrete values. *A digital thermometer does not show you temperature constantly, it just tells you whenever it changes
Digital Multi-Meter (DMM) A piece of test equipment used to measure voltage, current, and resistance in an electronic circuit DMM tells us the voltage running through the circuit is -4.75
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 by three. Engineering Notations make calculations easier
Kirchhoff's Current Law (KCL) Th algebraic sum of all currents into and out of any branch point in a circuit must equal 0 KCL does not allow the sum of currents to equal 1
Kirchhoff's Voltage Law (KVL) The algebraic sum of all voltages around any closed path must equal 0 Zack's calculations are wrong because he got 2 and KVL doesn't allow that
LED Light-emitting diode. An electronic device that conducts current in one direction only and illuminates when it is conducting. My TV's LED screen is amazing
Ohm Unit of resistance. Value of 1 ohm allow current of one ampere with potential difference of one volt. Ohm's can be measured with a DMM
Ohm's Law In electric circuits, I=V/R You can't find the OHM without voltage and ampere.
Parallel Circuit One that has two or more branches for separate currents from one voltage source A parallel circuit allows you to remove certain outlets and still allow the circuit to be closed and function properly.
Resistor Color Code Coding system of colored stripes on a resistor to indicate the resistor's value and tolerance You don't want the Resistor Color Code to pull up a not so good color (?)
Scientific Notation Numbers entered as a number from one to 10 multiplies by a power of 10 Scientific Notation and Engineering notation serve the same purpose
Series Circuit One that has only one path current. If you remove an outlet in a Series Circuit, the circuit will open and stop working
SI Notation Abbreviation of System International, a system of practical units based on the meter, kilogram, second, ampere, kelvin, mole, and candela An example of SI Notation would be for I representing ampere
Solder Metallic alloy of tin and lead that is used to join two metal surfaces. A solder is used a lot in the production of digital electronics
Soldering Process of joining two metallic surfaces to make an electrical contact by melting solder (usually tin and lead) across them Soldering allows certain connections on a motherboard to happen
Soldering Iron Tool with an internal heating element used to heat surfaces being soldered to the point where the solder becomes molted Be careful of the fumes Soldering Iron can omit.
