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. "Almost every 'analog' clock has the red second hand."
Breadboard A circuit board for wiring temporary circuits, usually used for prototypes or laboratory work. "The 'breadboard' is sometimes the building block for circuits."
Conventional Current The direction of current flow associated with positive chare in motion. The current flow direction is from positive to negative potential, which is in the opposite direction of electron flow. "Some circuits could have a 'conventional current' type flow."
Current A movement of electrical charges around a closed path or circuit. "I managed to get the 'current' to flow by closing the circuit."
Digital A way of representing a physical quantity by a series of binary numbers. A digital representation can have only specific discrete values. "A 'digital' clock only updates the time every minute."
Digital Multi-Meter (DMM) A piece of test equipment used to measure voltage, current, and resistance in an electronic circuit. "I used the 'digital multi-meter' to measure the voltage in my 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. "Some of my engineering answers are in 'engineering notation' form."
Kirchhoff's Current Law (KCL) The algebraic sum of all currents into and out of any branch point in a circuit must equal zero. "The way 'Kirchhoff's Current Law' is stated is that current stays the same in any circuit."
Kirchhoff's Voltage Law (KVL) The algebraic sum of all voltages around any closed path must equal zero. "The way 'Kirchhoff's Voltage Law' is stated is that voltage stays the same in any circuit."
LED Light-emitting diode. An electronic device that conducts current in one direction only and illuminates when it is conducting. "Many lights are 'LED' lights."
Ohm Unit of resistance. Value of one ohm allow current of one ampere with potential difference of one volt. "My resistor measures 1 'Ohm'."
Ohm's Law In electric circuits, I=V/R. "Some of my calculations require the 'Ohm's Law' formula."
Parallel Circuit One that has two or more branches for separate current from one voltage source. "My classroom lights are a visual representation of a "Parallel Circuit'."
Resistance Opposition to current. Unit is the Ohm. "My resistors measure 'resistance' in ohms."
Resistor Color Code Coding system of colored stripes on a resistor to indicate the resistor's value and tolerance. "I took down notes of the 'Resistor Color Code' for my resistors."
Scientific Notation Numbers entered as a number from one to ten multiplied by a power of ten. "Another batch of my answers are in 'Scientific Notation'."
Series Circuit One that has only one path current. "This circuit I am working on 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. "Many countries use the 'SI Notation'."
Solder Metallic alloy of tin and lead that is used to join two metal surfaces. "I am holding a piece of 'solder'."
Soldering Process of joining two metallic surfaces to make an electrical contact by melting solder (usually tin or lead) across them. "I am 'soldering' my solder."
Soldering Iron Tool with an internal heating element used to heat surfaces being soldered to the point where the solder becomes molten. "I am using a 'Soldering Iron' to help with the soldering."

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.

To see how well you know the information, try the Quiz or Test activity.
