ANALYSIS OF AC SERIES CIRCUITS

In alternating current (AC) networks, the presence of reactive components (inductors and capacitors)

introduces a phase dependency between voltage and current. Unlike purely resistive DC circuits, the total

opposition to current in an AC circuit must account for both dissipative resistance and frequency-dependent

reactances. This guide explores the mathematical, physical, and phasor characteristics of series RL, RC, and

RLC configurations.
