Question

(i) Rank the following five capacitors from greatest to smallest capacitance, noting any cases of equality:

(a) a capacitor with a 4-V potential difference between its plates

(b) a  capacitor with charges of magnitude on each plate  

(c) a capacitor with charges of magnitude on its plates, differing by 2 V in potential.

(d) a capacitor storing energy  

(e) a capacitor storing energy with a 10-V potential difference

(ii) Rank the same capacitors in part (i) from largest to smallest according to the potential difference between the plates.

(iii) Rank the capacitors in part (i) in the order of the magnitudes of the charges on their plates.

(iv) Rank the capacitors in part (i) in the order of the energy they store.
