Steps to Analyze AC Circuits:
  • Transform the circuit to the phasor or frequency domain.
  • Solve the problem using circuit techniques (nodal analysis, mesh analysis,     superposition, etc.).
  • Transform the resulting phasor to the time domain.
4
10.2 Nodal Analysis (1)
  • Example 1
  •   Using nodal analysis, find v1 and v2 in the circuit of figure below.
5
10.3 Mesh Analysis (1)
  • Example 2
  •    Find Io in the following figure using mesh analysis.
6
10.4 Superposition Theorem (1)
  •    When a circuit has sources operating at different frequencies,
    • The separate phasor circuit for each frequency must be solved independently, and
    • The total response is the sum of time-domain responses of all the individual phasor circuits.

10.4 Superposition Theorem (2)
  • Example 3
  •    Calculate vo in the circuit of figure shown below using the superposition theorem.
