Establish the equivalence between Thevenin’s and Norton’s theorems.
An ideal voltage source can be thought of being a Thevenin equivalent circuit of itself for the special case where series resistance is zero. The Nortorn equivalent circuit of such c circuit would have infinite current which does not exist. Similarly an ideal current source is considered to be a Norton equivalent circuit with an infinite value of resistor (open – circuit) in shunt with it. In this case the Thevenin’s equivalent would have infinite voltage and does not exist.
