- Example 1
- If R = 10 Ω, L = 5 H,
and C = 2 mF in 8.8, find
α, ω0, s1 and s2.
- What type of natural response
will the circuit have?

- Example 2
- The circuit shown below has
reached steady state at t = 0-.
- If the make-before-break switch
moves to position b at t = 0, calculate i(t) for t > 0.
