Practice Exercises 2.6
You have five 10.0 F capacitors. Show all the possible connections for the five capacitors to
produce a total capacitance of 50.0 F.
Suppose the space between the plates of the capacitor in Sample
Problem 2.6 item number 2 is filled with equal thicknesses of the same
dielectrics but arranged as shown. What is its capacitance?

The capacitors in Sample Problem 2.6 item number 3 are connected in
parallel instead of being in series. The combination is connected to a
100 V line. Find the (a) total capacitance, (b) charge stored in each capacitor, and (c) potential
difference across each capacitor.

Practical Science
The touch screen of laptops, cell phones, and other similar devices
works on the principle of series combination of capacitors. Two parallel
layers of transparent conducting oxides (like iridium tin oxide) maintained
at constant voltage are positioned behind the screen. These two layers form
a capacitor. When the screen is touched with a finger at one point, the
finger and the outer layer form another capacitor in series with the previous
capacitor. A microprocessor detects this change and interprets which part
is pressed. Similarly, in a capacitive keyboard, each key is connected to a pluno
rated by a dielec
