FLASHCARD QUESTION
Front
Electric Charge Noun
[uh-lek-trik charj]
Back
Electric Charge
A fundamental property of matter, carried by particles like electrons, that causes it to experience a force in an electromagnetic field.
Example: This image compares the random movement of electric charges (electrons) in a conductor to their organized flow when a voltage is applied.

FLASHCARD QUESTION
Front
Current Noun
[kur-uhnt]
Back
Current
The rate at which electric charge flows through a conductor or circuit, typically measured in units called amperes (A).
Example: A battery powers the flow of charged particles through a conductor (wire), creating an electric current that lights up a bulb.

FLASHCARD QUESTION
Front
Voltage Noun
[vohl-tij]
Back
Voltage
The difference in electric potential energy between two points that provides the 'push' for current to flow through a circuit.
Example: This image shows that just like the height of water in a pipe creates pressure to make it flow, voltage is the 'pressure' that pushes electricity.

FLASHCARD QUESTION
Front
Resistance Noun
[ri-zis-tuhns]
Back
Resistance
The opposition to the flow of electric current within a material or component, measured in units called ohms (Ω).
Example: The light bulb in this circuit acts as a resistor, opposing the flow of electricity and converting electrical energy into light and heat.
5.
FLASHCARD QUESTION
Front
Load Noun
[lohd]
Back
Load
A component in an electrical circuit that consumes electrical energy and converts it into another form, such as light or heat.
Example: In an electrical circuit, the load is the component that uses energy, like this lightbulb which converts electrical energy into light.

FLASHCARD QUESTION
Front
Ohm's Law Noun
[ohmz law]
Back
Ohm's Law
A fundamental principle stating the direct proportionality between the voltage across a conductor and the current flowing through it.
Example: This diagram shows a simple circuit with a voltage source (V), a resistor (R), and the resulting current (I), illustrating Ohm's Law (I=V/R).
7.
FLASHCARD QUESTION
Front
Conductor Noun
[kuhn-duhk-ter]
Back
Conductor
A material that allows electric current to flow through it easily due to the presence of mobile, loosely bound electrons.
Example: This image shows a penny completing a simple circuit, causing a bulb to light up. This demonstrates that the metal penny is a conductor.
