    Study Notes

    Definition

    A microfarad (μF) is a unit of capacitance in the metric system, equal to one millionth of a farad.

    Conversion

    1 microfarad (μF) = 0.000001 farads (F)

    Capacitance Measurement

    Microfarads are used to measure the capacitance of capacitors, which store electric energy in an electric field.

    Common Values

    • Small capacitors: 10-100 μF
    • Medium capacitors: 100-1000 μF
    • Large capacitors: 1000-10000 μF or more

    Applications

    • Filtering and regulation in electronic circuits
    • Energy storage in power supplies and motor control systems
    • Coupling and decoupling in audio and radio frequency circuits
