The switch in the circuit seen in fig. p7.52 has been in position a for a long time. At t=0, the switch moves instantaneously to the position b. For t >= 0+, find i0(t).
Figure 1 shows the modified circuit when t < 0.
Figure 2 shows the modified circuit when t > 0.
Figure 3 shows the Thevenin resistance at t...
