Problem

Which of the following equations correctly defines the capacitance

C

of a parallel-plate capacitor in terms of the magnitude of charge

Q

on either plate and the potential difference

\Delta V

between the plates? a)

C = \dfrac{1}{2}\,\dfrac{Q}{\Delta V}

C = 2\,\dfrac{Q}{\Delta V}

C = \dfrac{Q}{\Delta V}

C = \sqrt{2}\,\dfrac{Q}{\Delta V}
