(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

2. Relevant equations

afaik, flux in inductor = Li.

at t=0, current through L is 0. so change of flux = LΔi = L(i-0)=Li

3. The attempt at a solution

at t=∞, i through cap. is 0.

so,

i get the following equations:

5(i1+i2)=20

5(i1+i2)+ 5i_{2}=10

i get i2=-2 and i1 = 6

i through indctor = i1+i2 = 4

so, flux=Li= 0.5*4=2

book's ans. is different.
