In the circuit of figure, the switch is closed to position-1 for a long time. At t = 0 the switch position is changed from postion-1 to postion-2. Find an expression for the current i(t).

i(t) = (E/R) cos[1/√(LC)]t A

i(t) = (E/R) sin[1/√(LC)]t A

i(t) = (E/R) sin√(LC) t A

i(t) = (E/R) cos√(LC) t A

i(t) = (E/R) cos[1/√(LC)]t A

i(t) = (E/R) sin[1/√(LC)]t A

i(t) = (E/R) sin√(LC) t A

i(t) = (E/R) cos√(LC) t A
