Question
Define the capacitance of a capacitor. State and define the SI unit of capacitance.
✓
Answer
(1) Definition: The capacitance (capacity) of a capacitor is defined as the ratio of the charge on either conductor to the potential difference between the two conductors forming the capacitor.
(2) The SI unit of capacitance is the farad.
Definition: The capacitance of a capacitor is said to be one farad if a charge of one coulomb is required to increase the potential difference between the two conductors forming the capacitor by one volt.
1 farad $=1$ coulomb $/$ volt; $1 F =1 CN$
[Note : Capacitors in common electronic circuits are in microfarad $\left(10^{-6} F \right)$, nanofarad $\left(10^{-9} F \right)$ or picofarad $\left(10^{-12} F \right)$.]
