Definition

Noun: A unit of electrical capacitance equal to one trillionth (10⁻¹²) of a farad. It is used to measure very small capacitance values, commonly found in electronic components like integrated circuits and high-frequency filters.

Usage

The picofarad is a standard metric unit for quantifying capacitance in scientific and engineering contexts, particularly in electronics. - The capacitor in the tuning circuit has a value of 100 picofarads. - Typical ceramic disc capacitors are rated in the picofarad range.

Advanced Usage
  • Scientific Notation: Often abbreviated as pF in circuit diagrams and component labels.
    • The required capacitance is 470 pF.
  • Unit Conversion: A key subunit in the metric system for capacitance, where 1 picofarad = 0.000001 microfarads (µF).
Variants and Related Words
  • Farad (F): The base SI unit of electrical capacitance.
  • Microfarad (µF): A unit equal to one millionth (10⁻⁶) of a farad.
  • Nanofarad (nF): A unit equal to one billionth (10⁻⁹) of a farad.
Synonyms
  • pF (the standard abbreviation).
Noun
  1. a unit of capacitance equal to one trillionth of a farad
