TermDefinitionExample sentence
Breadboard A circuit board for wiring temporary circuits, usually used for prototypes or laboratory work. We will be using breadboards soon in digital electronics class to program prototypes to se if they work.
Conventional Circuit 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. A battery uses some type of conventional circuit since it is moving from positive side to negative side.
Current A movement of electrical charges around a closed path or circuit. The current is passing from pole line to pole line to get power.
Digital A way of representing a physical quantity by a series of binary numbers. A digital representation can only have only specific discrete values. My phone is powered and since it is digital it has all the power in one hand-holding device.
Digital Multi-Meter(DMM) A piece of test equipment used to measure voltage, current, and resistance in an electronic values I need a digital multi-meter so I can see how much volts this battery has.
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. I would need an engineering notation so that I would be able to figure out the solution.
Kirchoff's Current Law (KCL) The algebraic sum of all currents into and out of any branch point in a circuit must equal zero. I know that the output of a circuit not mattering where will always zero because of the kirchoff's current law.
Kirchoff's Voltage Law(KVL) The algebraic sum of all voltages around any closed path must equal zero. The kirchoff's voltage law allows me to put in a voltage and get an output result of zero.
LED Light-emitting diode. An electronic device that conducts current in one direction only and illuminates when it is conducting. The LED turned on when the robot detected it was dark.
Ohm Unit of resistance. Value of one ohm allow current of one ampere with potential difference of one volt. There are 30 ohms inside this toy while it is functioning.
Ohm's Law In electric circuits, I=V/R If I use I=V/R then I can find how many ohms there are.
Parallel Circuit One that has two or more branches for separate current from one voltage source I need to use a parallel circuit if I want to have two different currents of voltage at the same time.
Resistance Opposition to current. Unit is the ohm. Resistance is what I need to see how much I power I can put in.
Resistor Color code Coding system of colored stripes on a resistance to indicate the resistor's value and tolerance. If I have the Resistor Color Code I can find out how much I need to make this circuit work.
Scientific Notation Numbers entered as a number from one to ten multiplied by a power of ten. The scientific notation helps me figure out the amount of power I need for this processor.
Series Circuit One that has only path current. Series Circuit act like train tracks which they follow one track.
SI Notation Abbreviation of System International, a system of practical units based on the meter, kilogram, second, ampere, Kelvin, mole, and candela. The SI notation helped me figure out what kind of power a light bulb produced.
Solder Metallic alloy of tin and lead that is used to join two metal surfaces. I solder a pole to another so that I could make a barrier between me and my friend.
Soldering Process of joining two metallic surfaces to make an electric contact by melting solder(usually tin and lead) across them. I am soldering so that I can make something to hold up these roofs.
Soldering iron Tool with an internal heating element used to heat surfaces being soldered to the point where the solder become molten. The soldering iron helps me burn them so that they can become one.
Analog A way of representing some physically 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 uses more of frequent waves to connect.

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.
