Parts and what they mean

• Voltage phasor V (वोल्टता फ़ेज़र V) — An arrow of length vm rotating anticlockwise at angular speed ω.
• Current phasor I (धारा फ़ेज़र I) — Length im; for a resistor it lies along V at every instant.
• Vertical projections (ऊर्ध्वाधर प्रक्षेप) — vm sin ωt₁ and im sin ωt₁ — the actual values of v and i at that instant.
• Angle ωt₁ (कोण ωt₁) — The angle the phasors have turned through at time t₁.
• Rotation at ω (anticlockwise) (ω से घूर्णन (वामावर्त)) — One full turn = one cycle of the ac.
• v versus ωt (v बनाम ωt) — Traced by the projection of V as it rotates.
• i versus ωt (i बनाम ωt) — Traced by the projection of I.
• Instant t₁ (क्षण t₁) — Dots = the projections in (a): the same values.
• Phasor axes (फ़ेज़र अक्ष) — Angles are measured anticlockwise from the horizontal.
• Time axis (ωt) (समय अक्ष (ωt)) — Horizontal axis of graph (b).
