What is a common submultiple of a farad?

A microfarad is a common submultiple of a farad, defined as one-millionth of a farad (1 µF = 10^-6 F). It is frequently used in electronic circuits for filtering, decoupling, and timing applications due to its suitable capacitance range. The microfarad is part of a larger system of submultiples that are based on powers of ten, making it a convenient choice for representing capacitance in manageable quantities that are commonly encountered in practical scenarios.

Other submultiples such as picofarad and nanofarad are also valid, but in many cases, the microfarad is more widely applied in everyday electronics. A millifarad represents a larger submultiple at one-thousandth of a farad, which may be less practical for typical electronic applications when smaller values are needed. Therefore, while microfarad is just one of several correct answers, it stands out for its frequent use in real-world applications.
