Fig. 3: Capacitors in series. You can also replace one capacitor by putting two capacitors in parallel as shown in Fig. 4. In this case, a .0015 mfd capacitor can be replaced by a .001 mfd and a .0005 ...

Of course, we all know that capacitors are conceptually two conductors separated by a dielectric of some sort. But outside of air-variable capacitors you normally don’t see them looking like … ...
