(d) What will be the maximum energy stored in the capacitor if the switch remains closed?
9. In the circuit described above the battery is removed after several minutes have passed. Then the loop is completed without the battery so that the capacitor is connected to the resistor. (a) How much time is required to discharge the capacitor by 99% (i.e. it retains only 1% of its original charge)? (b) What is the current at that point?
