Thevenin Norton Equivalent. So a much quicker way to calculate the norton current in the example above would have been to use ohm s law. Sometimes it is desirable to convert thevenin s or norton s equivalent circuit into each other for easier and faster solving of circuits.
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. Sometimes it is desirable to convert thevenin s or norton s equivalent circuit into each other for easier and faster solving of circuits.
Thevenin and norton equivalent circuits are fundamental approaches to analyzing both ac and dc.
Thevenin and norton s resistances are equal. So a much quicker way to calculate the norton current in the example above would have been to use ohm s law. This equivalence between thevenin and norton circuits can be a useful tool in itself as we shall see in the next section. Norton current thevenin voltage equivalent impedance 10 58v 295 6 ohms 35 78 ma.
