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...

A capacitor with capacitance C is initially charged with charge q0. At time t = 0 a resistor with resistance R is connected across the capacitor. (Figure 1)
To understand the behavior of the current and voltage in a simple R-C circuit. A capacitor with capacitance C is initially charged with charge q0. At time t = 0 a resistor with resistance R is connected across the capacitor. (Figure 1) Part CNow solve the differential equation V(t) = -CR dV(t)/dt for the initial conditions given in the problem introduction to find the voltage as a function of time for any time t.
