capacitor

You have the right general idea, but you can''t just consider the two capacitors as one 3F capacitor. Just before the switch is closed, the 2F capacitor will be fully charged and (I presume) the 1F capacitor is fully discharged. So when the switch is closed, the 2F capacitor will discharge and the 1F capacitor will charge.

How Long Does It Take to Discharge a Capacitor?

This value yields the time (in seconds) that it takes a capacitor to discharge to 63% of the voltage that is charging it up. After 5 time constants, the capacitor will discharge to almost 0% of all its voltage. Therefore, the formula to calculate how long it takes a capacitor to discharge to is: Time for a Capacitor to Discharge= 5RC

With small capacitors up to 1 mF, there is little to worry about. I suppose it''s a good idea to make sure they are discharged before plugging them in where the voltage that could be on the cap could damage something, but this is something not generally worried about until you get to some real energies or high voltages.

Derivation for voltage across a charging and discharging capacitor

As we are considering an uncharged capacitor (zero initial voltage), the value of constant ''K '' can be obtained by substituting the initial conditions of the time and voltage. At the instant of closing the switch, the initial condition of time is t=0 and voltage across the capacitor is v=0. Thus we get, logV=k for t=0 and v=0.
