Norton Theorem

Any two-terminal linear electrical network, consisting of independent and dependent voltage and current sources, resistors, and other linear components, can be replaced by an equivalent circuit consisting of a current source (called Norton's current) in parallel with a resistor (called Norton's resistance).

If two identical 2 A, 2 Ω Norton equivalent circuits are connected in parallel, then:

\(R_N={2\times 2\over 2+2}=1\Omega\)

\(I_N=2+2=4A\)
