Unit 1.1 Part A

TermDefinitionExample 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. I have an analog clock on my wall.
Breadboard A circuit board for wiring temporary circuits, usually used for prototypes or laboratory work I used a breadboard first so that it would be easier to fix a problem f one arises.
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. Conventional Current travels from the positive side of the battery to the negative side.
Current A movement of electrical charges around a closed path or circuit. Current is what goes through your body when you touch an open and powered circuit.
Digital A way of representing a physical quantity by a series of binary numbers. A digital representation can have only specific discrete values. The clock on my phone is digital.
Digital Multi-Meter (DMM) A piece of test equipment used to measure voltage, current, and resistence in an electronic circuit The Digital Multi-Meter told me the voltage of the battery was 9V.
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. The way to write 365,219 in engineering notation is 365.219*10^3.
Kichhoff's Current Law (KCL) The algebraic sum of all currents into and out of any branch point in a circuit must equal zero KCL is usually associated with parallel circuits.
Kichhoff's Voltage Law (KVL) The algebraic sum of all voltages around any closed path must equal zero. KVL is usually associated with series circuits.
LED Light-emitting diode. An electronic device that conducts current in one direction only and illuminates when it is conducting. When I turn on the switch, the circuit should power the green LED.
Ohm Unit of resistance. Value of one ohm allow current of one ampere with potential difference of one volt. The resistor has a lot of Ohms in it.
Ohm's Law In electric circuits, I=V/R. I calculated the current of the circuit to be 1 mA using Ohm's Law.
Parallel Circuit One that has two or more branches for separate current from one voltage source. Christmas lights with all of the little LEDs is a parallel circuit.
Resistance Opposition to current. Unit is the ohm The more resistance there is, the less current goes trough.
Resistor Color Code Coding system of colored stripes on a resistor to indicate the resistor's value and tolerance. Using the Resistor Color Code, I can tell between the stronger and weaker resistors.
Scientific Notation Numbers entered as a number from one to ten multiplied by a power of ten. Scientific notation is not to be confused with engineering notation.
Series Circuit One that has only one path current. An on and off switch to a light bulb 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. The US is the only major country that hasn't adopted the SI Notation.
Solder Metallic alloy of tin and lead that is used to join two metal surfaces. The solder that I used to join these two metal poles together was made of lead.
Soldering Process of joining two metallic surfaces to make an electrical contact by melting solder (usually tin and lead) across them. Using soldering, I joined these two metal poles together.
Soldering Iron Tool with an internal heating element used to heat surfaces being soldered to the point where the solder becomes molten. The way that I soldered the two metal poles together was with a soldering iron.
