Alternating Current — Key Formulas
| Formula | Expression |
|---|---|
| AC Voltage | V = V₀ sin(ωt + φ) |
| RMS Value | V_rms = V₀/√2 |
| AC Power | P = V_rms × I_rms × cosφ |
| Impedance | Z = √(R² + (X_L − X_C)²) |
| Capacitive Reactance | X_C = 1/ωC |
| Inductive Reactance | X_L = ωL |
| Phase Angle | tanφ = (X_L − X_C)/R |
| Resonant Frequency | f = 1/(2π√LC) |
