A 16 V battery, a resistor with R = 10^6Ω and a 6-μF capacitor are connected in series with a switch. Find the time taken for the capacitor;
a)To charge to a voltage value of 12V
b)Time to discharge to a value to 7V, after it has fully charged to 16V
To start this problem I figure I need to find the Time constant T=RC, which is 10^6Ω*6μF =6e^6s.
Now I am stuck on how to find the charging and discharging times. If someone could point me in the right direction I would be greatly appreciated. I think I have to use the formula Vc = V(1 - e-t/RC) , but Im not sure how to do this. I assume for part a I plug in the 12V value somewhere, but Im not sure where.
Any suggestions?
