How capacitors discharge

WebA capacitor is fully charged to 10 volts. Calculate the RC time constant, τ of the following RC discharging circuit when the switch is first closed. The time constant, τ is found using the formula T = R*C in seconds. Therefore the … WebThe general equation for the voltage across the capacitor is. t = C ( V − V 0) I = 1 F ( 3 V − 5 V) − 10 m A = 200 s = 3 minutes and 20 seconds. The more general solution is where I is a function of time. I'll assume that the 10mA is the initial current, at V 0 = 5V. Then the discharge resistor R = 5 V 10 m A = 500 Ω.
