Thevenin Equivalent Circuit 2 Voltage Sources. Transform this back to a thevenin equivalent 19 2 volts in series with 4 ohms. 1 27 3 the thevenin equivalent circuit.

The french engineer leon charles thevenin 1857 1927 stated the principle of this equivalence as a theorem. Likewise the 12 volt source and 5 ohm resistor become a 2 4 a source in parallel with a 5 ohm resistor. Some circuit two terminals two nodes port v th r th thevenin equivalent some circuit r l load v rl v th r th r l load v rl need to determine v th and r.
Any two terminal network of fixed resistances and voltage sources may be replaced by a single voltage source that has.
Is the open circuit voltage shown in fig. From this you can use a voltage divider between the two 150ohm resistors getting a value of 6v. Is the open circuit voltage shown in fig. Now we should find an equivalent circuit that contains only an independent voltage source in series with a resistor as shown in fig.
