The solution finds the Thevenin's and Norton's equivalent circuits of network.
a) Thevenin's Theorem
Any combination of batteries and resistances with two terminals can be replaced by a single voltage source e and a single series resistor r. The value of e is the open circuit voltage at the terminals AB, and the value of r is e divided by the current with the terminals short circuited.
b) Norton's Theorem
Any collection of batteries and resistances with two terminals is electrically equivalent to an ideal current source i in ...
