The formula which calculates the capacitor current is I= Cdv/dt, where I is the current flowing across the capacitor, C is the capacitance of the capacitor, and dv/dt is the derivative of the voltage across the capacitor. You can see according to this formula that the current is directly proportional to the derivative of the voltage.
The other use of the term "breakdown" in electronics is for breakdown voltages in diodes. For capacitors in series, 1/C [total] = 1/C + 1/C + 1/C +... For caps in parrallel, C [total] = C + C + C + ... The current and v0ltage are related by i = C (dV/dt), which are just derived from the equation Q=CV.

This article explains some basic parameters of capacitors – insulation resistance, DCL leakage current and breakdown voltage / withstanding voltage. Important feature of capacitor apart its capacitance is: its ability to keep the charge for some time without self-discharging due to its internal leakage (conductivity) mechanisms.
The current and v0ltage are related by i = C (dV/dt), which are just derived from the equation Q=CV. The rated voltage for the capacitor will be on there.
Measurement of the IR and Leakage Current At an IR determination, one measures the DC leakage current through the capacitor. The measuring circuit, however, always contains a certain series of resistance. Hence we need to take into consideration the charging time. The circuit diagram and charging curve for a capacitor is shown in Figure 2.
