Parts and what they mean

• Source voltage phasor V (स्रोत वोल्टता फ़ेज़र V) — v = vm sin ωt.
• Current phasor I (धारा फ़ेज़र I) — Ahead of V by φ when XC > XL.
• Phase angle φ (कला कोण φ) — tan φ = (XC − XL)/R. Between 0 and π/2 (never a full π/2 while R ≠ 0).
• Anticlockwise rotation at ω (ω से वामावर्त घूर्णन) — Both phasors rotate together.
• Voltage v (वोल्टता v) — Red curve.
• Current i (धारा i) — Blue curve: reaches its peak earlier than v.
• Phasor axes (फ़ेज़र अक्ष) — Angles measured anticlockwise.
• Time axis (ωt) (समय अक्ष (ωt)) — Horizontal axis of graph (b).
