TermDefinitionEx. 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. The Analog button for my thermostat was set low.
Breadboard A circuit board for wiring temporary circuits, usually used for prototypes or laboratory work. My breadboard was overheated to the point it burned out. I had to get a new one.
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 electrical flow. My convential current from my xbox powercord was a strong charge.
Digital A way of representing a physical quantity by a series of binary numbers. A digital representation can have only specific discrete values. My Digital camera has very good quality.
Digital Multi-Meter (DMM) A piece of test equipment used to measure voltage, current, and resistance in an electronic circuit. The schools digital multi meter has gone missing because the students do not take care of them.
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 An engineering notation problem was used on the daily quiz.
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 got Kirchhoff's current law while trying to take my test.
Kirchhoff's Voltage law The algebraic sum of all voltages around any closed path must equal zero Kirchhoff's voltage law needed to be used in finding the circuit.
LED Light-emitting diode. An electronic device that conducts current in one direction only and illuminates when it is conduction. I installed LED lights in my room to set the mood.
Ohm Unit of resistance. Value of one ohm allow current of one ampere with potential difference of one volt. Ohm in 1827, and since known as Ohm's Law.
Ohm's Law In Electric Circuits, I=V/R Ohm's Law was used to solve my homework problem today.
Parallel Circuit One that has two or more branches for separate current from one voltage source. I made a parallel circuit drawing today apart of my warmup.
Resistance Opposition to current. Unit is the ohm. The resistance between on side of the rope was very weak.
Resistor Color Code Coding system of colored stripes on a resistor to indicate the resistor's value and tolerance. The resistor's Color code was very rgb like.
Scientific Notation Numbers entered as a number from one to ten multiplied by a power of ten. The scientific notation for 4 was used in our test today.
Series Circuit One that has only one path current. In class today we created a series circuit as a project.
Si Notation Abbreviation of system international, a system of practical units based on the meter, kilogram, second, ampere, Kelvin, mole, candela. The Si Notation for Kilogram was Kilo.
Solder Metallic alloy of tin and lead that is used to join two metal surface. Solder was a new metallic alloy of tin we found out about in class today.
Soldering Process of joining two metallic surfaces to make an electrical contact by melting solder (usually tin and led) across them. The two metals were soldering because it made contact with the other surface.
Soldering Iron Tool with an internal heating element used to head surfaces being soldered to the point where the solder becomes molten. In class our teacher gave an example on how to use a soldering iron.
Current A movement of electrical charges around a closed path or circuit. The current flow of water running through my pipe was very fast.

Use these flashcards to help memorize information. Look at the large card and try to recall what is on the other side. Then click the card to flip it. If you knew the answer, click the green Know box. Otherwise, click the red Don't know box.

When you've placed seven or more cards in the Don't know box, click "retry" to try those cards again.

If you've accidentally put the card in the wrong box, just click on the card to take it out of the box.

You can also use your keyboard to move the cards as follows:

• SPACEBAR - flip the current card
• LEFT ARROW - move card to the Don't know pile
• RIGHT ARROW - move card to Know pile
• BACKSPACE - undo the previous action

If you are logged in to your account, this website will remember which cards you know and don't know so that they are in the same box the next time you log in.

When you need a break, try one of the other activities listed below the flashcards like Matching, Snowman, or Hungry Bug. Although it may feel like you're playing a game, your brain is still making more connections with the information to help you out.
