The Ccb capacitor appears as itself (Ccb) when the transistor is off or
firmly saturated (because dUc ~= 0 on both cases). It has the value
beta*(1+Ccb) when the transistor is in the dynamic region (between off and
saturated). The resistor (coil) load will essentially have the entire
supply voltage across it after a certain Ic will  have been reached.
