Tutorial Four
1. Assuming that the switch in Fig. 1 has been in position A for a long time and is moved to
position B at t=0, find v0(t) for t≥0.
Fig. 1
2. Find i(t) and v(t) for t>0 in the circuit of Fig. 2 if i(0) = 10A.
Fig. 2
3. (a) If the switch in Fig. 3 has been open for a long time and is closed at t=0, find v0(t);
(b) Suppose that the switch has been closed for a long time and is opened at t=0, find
v0(t).

4. For the network shown in Fig. 4, find v(t) for t>0.

5. Consider the circuit in Fig. 5. Find i(t) for t<0and t>0.
