(b) Consider a random circuit as in Figure Q.2 (b). Figure Q.2(b) Note: $$\mathrm{S}1=\mathrm{S}2=$$ The switches will be $$\mathrm{ON}$$ when $$\mathrm{t}>0$$ S3= The switch will be OFF when $$t>0$$ (i) Draw the circuit in $$S$$-domain for $$\mathrm{t}>0$$ by assuming initial current value is $$10\mathrm{A}$$ $$(2$$ marks) (ii) Find the circuit current, $$I(s)$$ for $$t>0$$. Then by using Inverse Laplace Transform, find $$i(t)$$. $$(4$$ marks) (iii) Find the voltage, $$\mathrm{Va}(\mathrm{t})$$ and $$\mathrm{Vb}(\mathrm{t})$$ for $$\mathrm{t}>0$$ (2 marks)
