Given linear two port network, its voltage and current plot at port 2 [V2 versus - I2 ] and load circuit is shown below,
Open circuit voltage across terminal AB,
V ∝ Vth = 5 V [From V2 and -I2 plot where I2 = 0]
From V2 and -I2 plot,
For V2 = 4V, I2 = -4mA
Thus, figure (a) can be replaced by thevenin’s equivalent circuit as,
Applying KVL in loop shown,
Replace the resistance R with the load circuit given in figure (c) in thevenin’s equivalent circuit.
Applying KVL in loop shown,
Hence, the value of current I2 is 4.
