In an RLC circuit, assume ω, and ω2 such that 1(joi) = 1(ju).) = Imax/V2 and Δω such that Δω-: ω2-ω| . In other words, Δω is the width of the current curve where the current has fallen to 1/V2 = 0.707 of its maximum value at the resonance frequency. At these frequencies, the power dissipated in a resistance becomes one-half of the dissipated power at the resonance frequency (they are called the half-power points). In an RLC circuit with...
