A network of identical capacitors and switches is shown. Clicking on the following configurations will open and close the switches, changing the properties of the network.

Configuration A
Configuration B
Configuration C
Configuration D
Configuration E

Rank the configurations according to the total capacitance (equivalent capacitance), from largest to smallest, using the symbols ">" and "=". (For example, "D>A=B>C".)
[A=D>C>E>B ]

Which, if any, of the configurations have capacitors that do not become charged?

C
A
A & D
C & E - Correct!
E
D
B
None of the configurations
