About AC Circuits

Capacitors and inductors are reactive components that store energy in electric and magnetic fields respectively. Their behavior in AC circuits is frequency-dependent and creates phase shifts.

Key Concepts:
  • Reactance (XL, XC)
  • Impedance (Z)
  • Phase relationships
  • Resonance phenomena
  • Quality factor (Q)
Basic Formulas
Capacitive Reactance:
XC = 1/(2πfC)
Inductive Reactance:
XL = 2πfL
Resonant Frequency:
f0 = 1/(2π√LC)
Learning Tips
Understanding AC:

Start with basic reactance calculations, then explore resonance phenomena. Understanding phasor diagrams helps visualize AC circuit behavior.

Safety Note:

Capacitors can store dangerous charges even when power is off. Always discharge capacitors safely before handling.
