Parts and what they mean

• Curve (i): R = 100 Ω (वक्र (i): R = 100 Ω) — At ω0, Z = R, so im = vm/R = 100/100 = 1.0 A.
• Curve (ii): R = 200 Ω (वक्र (ii): R = 200 Ω) — Peak is half: im = 100/200 = 0.5 A.
• Resonant frequency ω0 (अनुनादी आवृत्ति ω0) — Where XL = XC. Here 1/√(10⁻³ × 10⁻⁹) = 10⁶ rad/s. It does not depend on R.
• Axes (अक्ष) — Horizontal: angular frequency of the source; vertical: current amplitude.
