Homework Statement
In the given circuit (voltage source is V) , we have to find initial and final values of current and also di(0+)/dt , di2)0+)/dt , d2i1(0+)/dt2 .
Now , by intial and values of currents , does they mean i(0-) and i(0+) or the discharging or charging current??
nd how to form the equations to solve it out??
Homework Equations
The Attempt at a Solution
beforing closing the switch , the current across the inductor , say i(0-) = (R1+R2)i2 = i(0+)
when we close the switch , capacitor will be shorted , and inductor will be open-circuited , so the KVL equation in the first loop will be V-i1R=0 by differentiating we get di1(0+)/dt = 0 similarly , d2i1(0+)/dt2 =0
how we will solve for di2(0+)/dt and d2i2(0+)/dt2 then..??
