Question

An RLC circuit is driven by an AC generator. The voltage of the generator is VRMS - 82.2 V. The figure shows the RMS current through the circuit as a function of the driving frequency. 900 800 700 500 (vw) SW 500 400 300 200 100 0 100 200 300 400 500 600 700 800 900 driving frequency (H) What is the ohmic resistance of the RLC circuit? Please, notice that the resonance curve passes through a grid intersection point. MWM Tries 0/12 If the capacitance of the capacitor is C - 312.0 nF, then what is the inductance L of the inductor? SWM Tries 0/12 What is the power of the circuit when the circuit is at resonance? 1 Tries 0/12

Answer 1

we know that 2 2 = R? + (WL wc) At reasonance COL FWc)- w² = // con=le 1 Lowac A f ZER (at reasonce) Noms = irms R Vrms irms 82.2 = 91.332 3 R = 900 x 10 R = 91,332 ☺ La (pit f ²c 1 2.0 404479 H -9 L = (pre 4500 o)? x 312 x 10 L = 2,041 H (6) - E -3 ) x 82.2 = =73980x1013 = power lims Voms (900x10 p=73.98 W CC)
