    Capacitor discharge problem

    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...
