    Study Notes

    Electricity Overview

    • Electric circuits are closed loops that allow the flow of electrons.
    • Components are interconnected through electrical wires and a power source, commonly a battery.
    • The starting point of electron flow is termed the source, while the end point is called the return.

    Electric Circuit Symbols

    • Each component in an electric circuit is represented by a specific symbol in circuit diagrams.
    • Understanding these symbols is essential for interpreting and creating circuit layouts.

    Simple Circuit Components

    • Cell: Acts as the power source in the circuit.
    • Load: Also known as a resistor, typically represented by a light bulb that illuminates when the circuit is active.
    • Conductors: Generally made of copper with no insulation, connecting the load to the power source.
    • Switch: Functions as a gap in the circuit, allowing the user to open or close the circuit.

    Series Circuit Characteristics

    • In a series circuit, the same current flows through all components without branching.
    • Designed with a single path for current; if one component fails (e.g., a bulb), the entire circuit stops functioning.
    • Common example includes household decorative string lights.

    Parallel Circuit Characteristics

    • Parallel circuits allow electric current to flow through multiple paths simultaneously.
    • Each component maintains a constant voltage across its terminals, independent of others.
