5) In the circuit shown below, the switch had been in position a for a long time. At t= 0, the switch was moved instantaneously to position b, and stayed there for 0.1[s]. Then, at t= 0.1[s], the switch was moved instantaneously back to position a. and remained there. For the time periods 0 0.1[s], find the numerical expressions for the voltage VR(t), as defined in the circuit. R=10[N] R-20[N] t= 0.1[s] si J100[V] L- 200[V] 3[H] 2[H]
