The circuit shown has a source voltage of 440 V rms, resistance R = 250 , inductance
Question:
The circuit shown has a source voltage of 440 V rms, resistance R = 250 Ω, inductance L = 0.800 H, and capacitance C = 2.22 μF.
(a) Find the angular frequency ω0 for resonance in this circuit.
(b) Draw a phasor diagram for the circuit at resonance.
(c) Find these rms voltages measured between various points in the circuit: Vab, Vbc, Vcd, Vbd, and Vad.
(d) The resistor is replaced with one of R = 125 Ω. Now what is the angular frequency for resonance?
(e) What is the rms current in the circuit operated at resonance with the new resistor?
