The Thevenin resistance R Th is given by R Th = v oc i sh = 120Ω . i sh 1 4 A 1 6 A G a b 300Ω 200Ω 100Ω-+ 100 V C-+ 50 V G a b 300Ω 200Ω 100Ω C Direct determination of R Th from the independent source-less network: The independent source-less network can be con-structed as shown on the left side. It can be retraced as shown on the right. Then, R Th equals the paral-lel combination of 200Ω and 300Ω resistances and thus it equals 120Ω. a 200Ω 300Ω 100Ω C G C G b The Thevenin equivalent circuit is shown on the right.-+ 10 V 120Ω b a...
