A Norton equivalent circuit for an ac source consists of

  1. a current source in series with an impedance
  2. a voltage source in parallel with an impedance
  3. a voltage source in series with a resistor only
  4. a current source in parallel with an impedance

Answer

D. a current source in parallel with an impedance

Solution

Norton's theorem replaces a linear two-terminal network with a current source IN in parallel with the Thevenin impedance ZN=ZTh.
