Thevenin Norton Equivalent. Sometimes it is desirable to convert thevenin s or norton s equivalent circuit into each other for easier and faster solving of circuits. Norton current is equal to thevenin voltage divided by thevenin resistance.
15 min read in the open circuit and short circuit section we talked about looking into two terminals of a circuit treating the circuit otherwise as an unknown black box. Thevenin s theorem and norton s theorem both are important dc network analysis techniques or theorem. Hévenin s and norton s equivalent are circuit simplification techniques that focus on terminal behavior.
Thevenin voltage is equal to norton s current times norton resistance.
Norton s theorem states that a linear two terminal circuit can be replaced by an equivalent circuit consisting of a current source i n in parallel with a resistor r n where i n is the short circuit current through the terminals and r n is the input or equivalent resistance at the terminals when the independent sources are turned off. And it is clear that every circuit have both their thevenin and norton equivalent circuits for a terminal or load. This equivalence between thevenin and norton circuits can be a useful tool in itself as we shall see in the next section. Thevenin s theorem and norton s theorem both are important dc network analysis techniques or theorem.
