PHY 102 Coulomb's law and Electric Fields Objective Question
Take CBT

Question

A capacitor is a device that stores charge. How is its capacitance (C) defined, and what are its SI units?
Options
A <i>C</i> = <i>V</i>/<i>q</i>, in Coulombs
B <i>C</i> = <i>qV</i>, in Joules
C <i>C</i> = <i>q</i>/<i>V</i>, in Farads (F)
Correct Answer
D <i>C</i> = <i>q</i>/<i>V</i>, in Volts (V)
Correct Answer

Option C is the correct answer.

Detailed Explanation

Page 12 defines capacitance as 'Magnitude of charge on either conductor / Magnitude of potential difference between conductors' (C = q/V) and states 'For q in coulombs and V in volts, C is in farads (F).'

Hint

Capacitance measures a device's ability to store charge per unit voltage.
