## Homework Statement

In given network (voltage source V & switch K) , a steady state is reached with the switch k open .At time t=0 , switch k is closed. Find voltage across C before switch is closed? and i

_{1 }&i

_{2}at t=0

^{+}.Also values of di

_{1}/dt and di

_{2}/dt at t=0.

## Homework Equations

## The Attempt at a Solution

since , before closing the switch steady state has reached . so , capacitor will be open & inductor open. so current i

_{1}(0

^{-}) will be V/R

_{1}+R

_{2 }=i

_{1}(0

^{+}). And current i

_{2}(0

^{+}) =V/R

_{3}.

Now for voltage across capacitor before switch is closed , it'll be i1R2-Ldi1/dt but di1/dt is coming out be zero. so voltage should be i

_{1}R

_{2}. Also di

_{2}/dt is coming out to be zero.at t=0- .. Please check if it is correct or not??
