DC supply for Lc cirucit

jerry225

The problem statement, all variables and given/known data
switch is closed at t=0, when i=0,id=0 and vc=-50volts. Modify the circuit, without affecting time variation of i, ensure that energy supplied to 75v source was instead returned to the 100V source


Loop equations : i=(vl/25uH) + ( vc/100uF)
100=Ldi/dt + [1/c]integral[di/dt]
