Norton's equivalent current is in parallel with :

  • A.A resistor
  • B.A capacitor
  • C.An inductor
  • D.A voltage source

Answer: A

The Norton current source is in parallel with a resistor.

The Norton equivalent of a linear network is a current source \(I_{N}\), equal to the short-circuit current at the terminals, in parallel with the Norton resistance \(R_{N}\), the resistance seen at the terminals with all independent sources turned off. \(R_{N}\) is the same as the Thevenin resistance. For AC networks it becomes an impedance, but in the standard statement it is a resistance.

A capacitor or an inductor alone is not the Norton element. A voltage source in series with a resistance is the Thevenin equivalent; putting a voltage source in parallel with the current source would not describe the network at all.
