Basics of Electronics Challenge Vocabulary

Comprehensive vocabulary flashcards covering basic electronics principles, multimeter functions, and circuit components based on the Solar Cup 2022 Electronics Challenge transcript.

Voltage ($V$)

The difference in electrical potential at one point in a circuit in relation to another, measured in Volts ($V$). It is the pressure that pushes through a conducting loop to do work.

Current ($I$)

The amount of flow of electric charge in a circuit, specified as the charge per unit time crossing a given area, measured in Amperes ($A$).

Resistance ($R$)

The measure of the opposition a material offers to the flow of electric current, measured in Ohms ($\Omega$).

Parallel Circuit

A way of connecting circuit elements so that there are multiple paths for the charge to travel through the circuit.

Series Circuit

A way of connecting circuit elements so that there is only a single path for the charge to travel through the circuit.

Ammeter

A device used for measuring current which must be connected in series with the circuit elements.

Voltmeter

A device used for measuring voltage which must be connected in parallel across two points in the circuit.

Digital Multimeter (DMM)

A basic device for measuring voltage, resistance, current, and other properties of a circuit, capable of measuring both $DC$ and $AC$.

Breadboard

A $2" \times 3"$ flat white component with holes used to build circuits by pushing wires and elements into them without soldering.

Ampere ($A$)

The standard unit of measurement for electrical current.

Milliampere ($mA$)

A unit of current equal to one-thousandth of an Ampere ($10^{-3} \text{ A}$).

Microampere ($\text{µA}$ or "u")

A unit of current equal to one-millionth of an Ampere ($10^{-6} \text{ A}$).

Ohm ($\Omega$)

The standard unit of measurement for electrical resistance.

Hertz ($Hz$)

The unit of measurement for frequency.

$$DC$$

Abbreviation for Direct Current.

$$AC$$

Abbreviation for Alternating Current, represented by the symbol $\sim$.

Audible Continuity Test

A multimeter mode that uses a buzzer to indicate low resistance, confirming a connection between two points.

HOLD

A multimeter function that freezes the displayed value on the $LCD$ screen.

Kilo ($k$)

A multiplier used for resistance representing a value of $1000$.

Mega ($M$)

A multiplier used for resistance representing a value of $1,000,000$.

OL

A display reading on a multimeter indicating "Open Loop," meaning no electrical connection is present.

NCV

Abbreviation for Non-Contact Voltage.
