Six parallel-plate capacitors of identical plate separation have different plate areas A, different capacitances C, and different dielectrics filling the space betweenthe plates. Below is a generic diagram of what each one of these capacitors might look like.

Rank the capacitors on the basis of the charge stored on the positive plate.

Rank from largest to smallest. To rank items as equivalent, overlap them.

a, A = 2 cm²                                                                               d, A = 4 cm²

   C= 8 nF                                                                                         C = 2 nF

b, A = 8 cm²                                                                               e, A = 4 cm²

    C = 2 nF                                                                                        C= 1 nF

c, A = 2 cm²                                                                               f, A = 1 cm²

    C = 4 nF                                                                                       C = 1 nF
