Problem 1
The switch in the circuit in the following figure has been in position a for a long time. At t = 0, it moves
instantaneously from a to b.
a. Construct the s-domain circuit for t > 0
b. Find V0(s)
c. Find v0 (t) for t ≥ 0
Problem 2
Find v0 in the circuit shown in Fig. 2 if ig = 5u(t) mA. There is no energy stored in the circuit at t = 0.

Problem 3
There is no energy stored in the circuit in the following figure below at the time the sources are
energized.
a. Find I1 (s) and I2(s)
b. Use the initial- and final-value theorems to check the initial- and final-values of i1 (t) and i2(t)
c. Find i1(t) and i2(t) for t ≥ 0
