Electric Current Flashcards

Study Notes

Fundamental Concepts of Electric Current

Ampere: Unit measuring current flow; equals one coulomb per second.
Battery: Generates electricity through chemical reactions.
Electric Current: Continuous flow of electric charges in a conductor.

Electrical Components

Circuit Diagram: Visual representation showing electron flow path in a circuit.
Closed Circuit: Complete circuit allowing current to circulate; essential for functionality.
Open Circuit: Incomplete circuit; current does not flow, rendering it nonfunctional.

Materials and Their Roles

Conductor: Material used to transmit electricity or heat effectively.
Insulator: Material that obstructs heat and electron flow; used to protect and separate conductive parts.
Semiconductor: Material that can conduct electricity under certain conditions, crucial in electronic devices.

Circuit Elements

Electric Circuit: A pathway allowing electricity to flow, consisting of various components.
Switch: Device that opens or closes a circuit, facilitating control over current flow.
Resistor: A component that impedes current flow, used for regulating voltages and currents.

Measurement and Laws

Multimeter: Tool for measuring voltage, current, and resistance in circuits.
Ohm's Law: Principle stating that current is directly proportional to voltage; crucial for circuit analysis.
Voltage: Measurement of electric potential difference; determines the flow rate of electricity in a circuit.

Additional Concepts

Electrical Symbol: Notation used to denote components in circuit diagrams, simplifying communication about circuits.
Electric Resistance: Measure of opposition to current flow in a material, quantified in ohms.
