Answer Notes
The ability of a capacitor to store an electrical charge is known as its capacitance. The standard unit of measurement for capacitance is the Farad, named after the English scientist Michael Faraday.
To put it into perspective, one Farad is defined as the capacitance when one Coulomb of charge causes a potential difference of one Volt across the plates. Because a full Farad is a massive amount of capacitance, radio circuits usually utilize components measured in microfarads or picofarads.
Distractors like Watt, Volt, and Coulomb measure different electrical properties (power, electrical potential, and discrete electrical charge, respectively) rather than the component's capacity to store that charge.
