hi all, wonderign whether you can help with this problem with capacitor discharging. take a look at the pic the question is In the circuit shown above, the switch has been in the upper position for a long time and moves to the lower position at t = 0. Find i(t). Basically, first i wanted to find out wat the voltage between the capacitor terminals would be after the long time it had been in the upper position. I found this as 20/3 V using thevenins theorem. now, i(t) is given in the textbooks as [-V*e^(-t/RC)]/R where V is the voltage across the OC capacitor. however, the discharge circuit the capacitor is connected is not just a simple circuit which contains only resistors - it contains a voltage source. how can i get an expression for i(t) in the discharge circuit? or am i going about this the wrong way. thank you. EDIT: Im not supposed to post this here, but i can find no way to delete the thread?
