26. Capacitors & Dielectrics

What is the equivalent capacitance of the following capacitors?

For the system of capacitors shown in Fig. E$24.16$, find the equivalent capacitance between $b$ and $c$.

You need a capacitance of 50 μF, but you don't happen to have a 50 μF capacitor. You do have a 75 μF capacitor. What additional capacitor do you need to produce a total capacitance of 50 μF? Should you join the two capacitors in parallel or in series?

Find expressions for the equivalent capacitance of (a) N identical capacitors C in parallel and (b) N identical capacitors C in series.

Each capacitor in FIGURE CP26.83 has capacitance C. What is the equivalent capacitance between points a and b?
