Phase Angle and Power Factor (tan φ = (X_L−X_C)/R; power factor = cos φ)
jee-mainjee-advancedneet-ug
tan φ = (X_L−X_C)/R; power factor = cos φ
What each symbol means
| Symbol | What it stands for |
|---|---|
| R | Resistance (Ω) |
| φ | Phase by which voltage leads current in series LCR (rad) |
| X_C | Capacitive reactance (Ω) |
| X_L | Inductive reactance (Ω) |
When to use this
Series LCR; φ > 0 means voltage leads current (more inductive than capacitive).
