179. In figures (a) and (b), the capacitors and batteries are identical. If the charge on each capacitor in figure (a) is $q_1$, and we name the charge on each capacitor in figure (b) $q_2$, what is the ratio $\dfrac{q_1}{q_2}$?

[Figure: Two circuit diagrams labeled (a) and (b), each containing capacitors and a battery. In (a) capacitors are in series; in (b) capacitors are in parallel.]
