How can I quickly and safely discharge a charged …
$begingroup$ I don''t think this will completely discharge the capacitor, at least not through the transistor. You need the voltage across R6 to be about 0.6V if the transistor is going to be active. That means the voltage …
Capacitor Discharge Time Calculator (with Examples)
The discharge time of a capacitor is primarily governed by the RC time constant (often denoted as τ), where R is the resistance through which the capacitor discharges, and C is the capacitance. The time constant represents the time required for the voltage across the capacitor to decrease to about 36.8% (substitute t=RC in the equation e −t/RC .
