Lesson 1.1 - Edwin

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. Ex. We used the analog clock to tell the time.
Breadboard A circuit board for wiring temporary circuits, usually used for prototypes or laboratory work. Ex. The boy used a breadboard to make a temporary timer circuit.
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. Ex. The technician new that the current would flow from positive to negative because it was a conventional current.
Current A movement of electrical charges around a closed path or circuit. Ex. The surge of electricity caused a current in the circuit.
Digital A way of representing a physical quantity by a series of binary numbers. This representation can have only specific discrete values. Ex. The girl used the digital clock to tell the time.
Digital Multi-Meter (DMM) A piece of test equipment used to measure voltage, current, and resistance in an electronic circuit. Ex. The technician used the digital multi-meter to make sure the electric current was off.
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 in some multiple of three. Ex. The engineer used engineering notation to simplify numbers
Kirchoff's Current Law (KCl) The algebraic sum of all currents into and out of any branch point in a circuit must equal zero. Ex. He used Kirchhoff's current law to calculate the sum of all the circuits currents.
Kirchoff's Voltage (KVL) The algebraic sum of all voltages around any closed path must equal zero. Ex. the engineer used Kirchhoff's voltage to calculate the voltage.
LED Light-emitting diode. An electronic device that conducts current in one direction only and illuminates when it is conducting. Ex. The store used LED lights to light up it's sign.
Ohm Unit of resistance. Value of one ohm allows current of one ampere with potential difference of one volt. Ex. The current had to deal several Ohm's of resistance.
Ohm's Law Explains the electric relationship of voltage, current, and resistance. In electric circuits, I=V/R. Ex. The engineer justified her circuit's values using Ohm's law
Parallel Circuit One that has two or more branches for current flow from one voltage source. Ex. The man plugged his charger into the socket of the parallel circuit.
Resistance Opposition to current. Unit is the ohm. Ex. The current met resistance when the circuit was turned on.
Resistor Color Code Coding system of colored stripes on a resistor to indicate the resistor's value and tolerance. Ex. The organizer used the resister color code to label the resistors.
Scientific Notation Numbers entered as a number from one to nine and a decimal, multiplied by a power of ten. Ex. The scientist used scientific notation to simplify the sum of their decimal
Series Circuit One that has only one path for current to flow. Ex. The Christmas light's bud brunt out so none of them lit up because it's 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. Ex. The scientist wrote the kelvin of the item in SI notation.
Solder Metallic alloy of 60% tin and 40% lead that is used to electrically join two metal surfaces. Ex. John works at a utility and hardware store where he sells things like solders and other tools.
Soldering Process of joining two metallic surfaces to make an electrical contact by melting solder (usually tin and lead) across them. Ex. The engineer connected the circuit by soldering them both together.
Soldering Iron Tool with an internal heating element used to heat surfaces being soldered to the point where the solder becomes molten. Ex. The instructor used the soldering iron while he was soldering to join the circuit.

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:

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.
