FAQ
Frequently Asked Questions
The symbol is µF, where µ (mu) is the Greek letter for 'micro-' and F stands for farad.
It is a relatively small unit for everyday electronics. A typical phone charger might use capacitors rated from 1 to 1000 µF. A farad itself is a very large unit.
A microfarad is one million times larger than a picofarad. 1 µF = 1,000,000 pF. Picofarads are used for very small capacitances, like in radio frequency circuits.
Yes, the standard plural is 'microfarads' (e.g., 'capacitors rated at 10 and 22 microfarads').
A unit of electrical capacitance equal to one millionth (10⁻⁶) of a farad.
Microfarad is usually formal, technical in register.
Microfarad: in British English it is pronounced /ˈmaɪ.krəʊˌfær.æd/, and in American English it is pronounced /ˈmaɪ.kroʊˌfær.æd/. Tap the audio buttons above to hear it.
Learning
Memory Aids
Mnemonic
Think: MICRO (very small) + FARAD (the unit named after Michael Faraday). A microfarad is a tiny fraction of a farad.
Conceptual Metaphor
A microfarad measures electrical 'storage capacity', analogous to a small bucket's capacity to hold water.
