FLASHCARD QUESTION

Front

Circuit Noun

[sur-kit]

Back

Circuit


A complete and closed path around which an electrical current can flow, typically including a source of electrical energy.

Example: This image shows a complete circuit where electricity flows from a battery, through a wire, to a light bulb, and back, causing the bulb to light up.

FLASHCARD QUESTION

Front

Current Noun

[kur-ent]

Back

Current


The rate of flow of electric charge through a point in a circuit, measured in units called Amperes (A).

Example: This diagram shows a simple circuit where electric current flows from a battery, through a switch and wire, to power a lightbulb.

FLASHCARD QUESTION

Front

Resistance Noun

[ri-zis-tans]

Back

Resistance


A measure of the opposition to the flow of electric current through a material, measured in units called Ohms (Ω).

Example: Using a water pipe analogy, this image shows resistance as a narrow section that squeezes and slows the flow of current pushed by voltage.

FLASHCARD QUESTION

Front

Resistor Noun

[ri-zis-ter]

Back

Resistor


An electrical component designed to implement a specific amount of electrical resistance in a circuit to control current flow.

Example: This cutaway diagram shows the parts of a resistor, including the metal leads, insulation, and the internal resistance material that slows down electricity.

FLASHCARD QUESTION

Front

Series Circuit Noun

[seer-eez sur-kit]

Back

Series Circuit


An electric circuit in which all components are connected end-to-end, providing only one path for the current to follow.

Example: This image shows a series circuit where electricity flows from a battery, through a switch and a light bulb, and back to the battery in a single, unbroken path.

FLASHCARD QUESTION

Front

Ammeter Noun

[am-mee-ter]

Back

Ammeter


An instrument used for measuring the electric current flowing through a specific point in an electrical circuit.

Example: This diagram shows how an ammeter is connected in a series circuit to measure the electric current flowing from a battery to a lamp.

FLASHCARD QUESTION

Front

Power Noun

[pou-er]

Back

Power


The rate at which electrical energy is transferred or converted into another form, such as light, heat, or motion.

Example: This diagram shows how rotating a wire coil in a magnetic field generates electrical energy, which provides power to light up the bulb.
