A certain biomedical implant firm wishes to design a pace-
maker that requires a 200 fF capacitor in order to func-
tion properly (f = femto = 10−15). However, the smallest-
capacitance model of capacitor that they can acquire has
capacitance 1 pF = 1000 fF. Which of the following strate-
gies could the biomedical firm use?
(I) Assuming that the capacitor is normally air-filled,
they could insert a dielectric between the capacitor
plates with dielectric constant 5.
(II) Arrange 5 of the 1 pF capacitors in series.
(III) Arrange 5 of the 1 pF capacitors in parallel.
(a) I only
(b) II only
(c) III only
(d) I and II, but not III
(e) I and III, but not II
