The unit of capacitance is the farad (symbol: F). One farad is defined as one coulomb of charge stored per volt of potential difference across the capacitor. In simpler terms, it measures the ability of a capacitor to store electrical charge. The farad is a relatively large unit, so you will commonly encounter subunits like microfarads (μF), nanofarads (nF), and picofarads (pF) in practical electronic applications. These subunits represent fractions or multiples of a farad to express capacitance values commonly used in various electronic circuits.
