10.14: Discharge of a Capacitor through an Inductance and a Resistance
The switch is closed, and charge flows out of the capacitor and hence a current flows through the inductor. Thus while the electric field in the capacitor diminishes, the magnetic field in the inductor grows, and a back electromotive force (EMF) is induced in the inductor. Let (Q) be the charge in the capacitor at some time.

Where: I = current (A) I 0 = initial current before discharge (A) e = the exponential function t = time (s) RC = resistance (Ω) × capacitance (F) = the time constant τ (s) This equation shows that the faster the time constant τ, the quicker the exponential decay of the
circuit design
$begingroup$ Capacitors have limits on pulse current withstanding. You may not always find the information you want to find on this topic, but sometimes the capacitor datasheet or an app note will have it available. Also, shorting larger capacitors can give rise to higher energy sparks which may eject hot metal fragments.
21.6: DC Circuits Containing Resistors and Capacitors
A small resistance (R) allows the capacitor to discharge in a small time, since the current is larger. Similarly, a small capacitance requires less time to discharge, since less charge is stored. In the first time interval (tau = RC) after the switch is closed, the voltage falls to 0.368 of its initial value, since (V = V_0 cdot e^{-1} = 0.368 V_0).
