picofarad
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
-
