Example 3.13
Create the script fi le impedance_ plots that returns for the series RLC circuit shown in
Figure 3.69, over the range 100 ≤ ω ≤ 10,000 rad/s, the following plots:
- |Z(ω)| versus ω
- ∠Z(ω) versus ω
- Repeat parts 1 and 2 for the case where the three elements (R, L, and C) are connected
in parallel
R = 10 Ω
C = 12.5 μF
L = 5 mH
100 rad/s ≤ w ≤ 10,000 rad/s
