The fundamental measurement unit for capacitance is__________?
Show answer Hide answer
Answer: C. farad
Explanation
The farad is established internationally as the primary standard unit for quantifying electrical capacitance in circuits. Named after the pioneering physicist Michael Faraday, this unit measures a component ability to store electrical charge. Standard electronic component specifications always express capacitance values using farads or convenient submultiples like microfarads. A one farad capacitor stores one coulomb of electrical charge when a potential difference of one volt is applied. Because one farad is an extremely large amount of capacitance, most practical components use microfarads or nanofarads. Capacitance depends on physical geometry including plate surface area, separation distance, and the permittivity of the dielectric.
The henry is the standard unit used for measuring electrical inductance rather than electrostatic capacitance. The ohm serves as the fundamental unit of electrical resistance, measuring opposition to steady current flow. Farad per meter describes permittivity rather than the total capacitance of a discrete electronic component.
