Changing the capacitance changes the rise and fall and changing the voltage change the rise and fall times:
The formula of finding capacitance between 2 parallel plate is as follows:
C=ϵA/d
where A is area of the plate
d is the distance between two plates
ϵ determines the permittivity of the medium in which the plates are kept / connected
C is the capacitance of the Capacitor
The formula of finding the capacitance would be
C=Q/V
where Q is the plates' charge in Coulombs
V is the plates' voltage
So, Capacitance of capacitor is inversely proportional to the voltage and proportional to the Charge.
Therefore, Changing the voltage leads to rise and fall times
