A 20,000-cycle source is connected to a series and a 0.266-uf capacitor. An impedance coil, whose resistance and inductance are 25 ohms and 0.191 mh, respectively, is then connected in series with a variable resistor, after which the combination is paralleled with the R-C circuit. For what value of the variable resistor will the entire circuit be in resonance?
