Parts and what they mean

• Resistance R (प्रतिरोध R) — Base of the triangle (along the current).
• Net reactance XC − XL (नेट प्रतिघात XC − XL) — Perpendicular side. If XC > XL the circuit is capacitive (φ > 0, current leads).
• Impedance Z (प्रतिबाधा Z) — Hypotenuse: Z = √(R² + (XC − XL)²); im = vm/Z.
• Phase angle φ (कला कोण φ) — tan φ = (XC − XL)/R; cos φ = R/Z is the power factor.
• Impedance triangle (प्रतिबाधा त्रिभुज) — It is the voltage triangle of Fig 7.11(b) with every side divided by im.
