mind that a voltage source-series
resistance combination is equivalent to
(or replaceable by) a current source-
parallel resistance combination if, and
only if their

24. Definition of Thevenin’s Theorem

25. Convert the circuit shown in Fig., to a single voltage source in series with a single resistor.

26. Using Thevenin theorem, calculate the current flowing through the 4 ohm resistor of Fig.

27. For the circuit shown in Fig., calculate the current in the 10 ohm resistance. Use
Thevenin’s theorem only.

28. Find Thevenin’s equivalent circuit for the network shown in Fig. for the terminal pair AB.

29. Norton’s Theorem
This theorem is an alternative to the Thevenin’s theorem. In fact, it is the dual of Thevenin’s theorem.
Whereas Thevenin’s theorem reduces a two-terminal active network of linear resistances and generators
to an equivalent constant-voltage source and series resistance, Norton’s theorem replaces the network by
an equivalent constant-current source and a parallel resistance.
