OBJECTIVES AND INTENDED
OUTCOMESBy the end of this lesson the learner is
expected to :
1. Understand the steps to analyze AC circuits .
2. To obtain skills for analyze AC circuits by using Nodal and Mesh
Currents

Steps to Analyze AC Circuits:
1. Transform the circuit to the phasor or frequency domain.
2. Solve the problem using circuit techniques (nodal analysis, mesh analysis, superposition, etc.).
3. Transform the resulting phasor to the time domain.
