SUMMARY
The resonance angular frequency for an L-R-C series circuit with an inductance (L) of 0.270 H and a capacitance (C) of 3.80 µF is calculated using the formula ω = 1/√(LC). The voltage amplitude of the source is 120 V, but it does not affect the resonance frequency calculation. The impedance at resonance is minimized, leading to a condition where the inductive reactance (XL) equals the capacitive reactance (XC). This results in the equation ω = 1/√(0.270 H * 3.80 µF).
