Hi Winston....

resonant rise is the point at which the voltage in a capacitor / 
inductor system balance out and becomes " infinately" hi ( but cant 
really ever get there due to the resistive factors)

as you approach the value of the cap that is in balance with the 
inductor from the low end going upwards ( low uF to value balanced) the 
voltage rises. once the value is reached and you start going past the 
balanced value state of the cap the reso voltage begins to drop since it 
is no longer in balance.

you can "balance" a system in either 2 ways...   keep the inductor at a 
constant and change the cap value  or keep the cap constant and change 
the inductor value ( this is what we do when we tune a coil)
