For a series R.L.C circuit the inductor is variable. Source voltage is 200√2sin100πt. Maximum current obtainable by varying the inductance is 0.314 A and the voltage across the capacitor then is 300 V. Find the circuit element values
Under resonant conditions, Im = V/R and VL = VC.
∴ R = V/Im = 200/0.314 = 637 Ω, VC = Im × XCD = Im/ω0 C
∴ C = Im/ω0 VC = 0.314/100π × 300 = 3.33 μF.
VL = Im × XL = Im ω0 L; L = V1/ω0
Im = 300/100 π × 0.314 = 3.03 H
