In an rc circuit the power factor
WebSep 17, 2015 · If the resistor and capacitor is connected to a DC source, then it is neither leading nor lagging. If it is connected to an ac source, then the reactive part of the impedance will be capacitive overall (since no inductors are present) and hence the current will lead the voltage. (leading power factor). Answer link WebThe combination of reactive power and true power is called apparent power, and it is the product of a circuit’s voltage and current, without reference to phase angle. Apparent power is measured in the unit of Volt-Amps (VA) and is symbolized by the capital letter S. Calculating for Reactive, True, or Apparent Power
