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

(a) a 20-µF capacitor with a 4-V potential difference between its plates
(b) a 30-µF capacitor with charges of magnitude 90 µC on each plate
(c) a capacitor with charges of magnitude 80 µC on its plates, differing by 2 V in potential,
(d) a 10-µF capacitor storing energy 125 µJ
(e) a capacitor storing energy 250 µJ with a 10-V potential difference


1.e > a > b > d > c
2.e > d > a > b > c
3.c > b > a > d > e
4.b > a = c > d = e
