Consider a capacitor of capacitance C initially charged with charge Q. A second initially uncharged capacitor,...
Consider a capacitor of capacitance C initially charged with charge Q. A second initially uncharged capacitor, also of capacitance C, is subsequently connected in parallel to the first capacitor. It is straight forward to show that charge state of the combined system, when it reaches equilibrium, is one where the charge divides between the capacitors, so that each capacitor now carries charge Q=2. However, it is interesting to note that the energy stored in the capacitors has changed between the...

There are identical capacitors with capacitance C1 and several others with capacitance C2. The values of C1 and C2 must be defined but C1 and C2 are not accessible individually. Instead, there is a network with C1 and C2 connected in series and a network with C1 and C2 connected in parallel. Futhermore, There is a 260.0-VV battery. The total energy supplied by the battery can be measured when it is connected to the network by using instruments. When the parallel combination...

plate capacitor by with two aluminum foil sheets and on or more
transparency sheets in between them.
If the each aluminum sheet is 10 cm x 10 cm, and a piece of
transparency is ~0.1mm thick, what is the capacitance of the 2 foil
sheets separated by 1 transparency sheet? Note: pay close
attention to the units!
