WebElectrical Engineering questions and answers. A 25-H choke coil in a filter circuit of a power supply operates at 60 Hz. Find a.) its inductive reactance b.) the coil current flowing if the voltage across the coil is 105 V c.) the RMS, peak and average values of this current. WebPerfect resistors possess resistance, but not reactance. Perfect inductors and perfect capacitors possess reactance but no resistance. All components possess impedance, and because of this universal quality, it makes sense to translate all component values (resistance, inductance, capacitance) into common terms of impedance as the first step …
