Reactance

  • An alternating current (a.c.) circuit is affected by the inductance and capacitance of the circuit
  • This effect is called Reactance
  • There are two types, inductive and capacitive …
  • Inductive reactance: An inductor opposes changes in current
  • Capacitive reactance: A capacitor opposes changes in voltage
  • Value is expressed in Ohms
