Solution Summary

This solution contains step-by-step calculations to determine the time taken for each capacitor to reach 10.0 V and the current at the time.

Solution Preview

Please refer to the attachment.

1. Let the potential across each capacitor at t=0 be V. As the switch is closed, Charge on the capacitor will start discharging through the resistors. Hence, a current I will flow through the loop. As the capacitor discharges gradually, the potential across the capacitors goes on reducing, finally becoming zero. Current also correspondingly goes on reducing, finally becoming zero.

At any instant t, the ...
