So, if r moving like this are encountering-terminal first. So,-20+this is V this is r+this is+-. So, plus-same +V encountering-terminal first VThevenin = 0; that means,; that means,-20 and V=-80 = VThevenin; that means, VThevenin =-100 volt .
तो, अगर r इस तरह से आगे बढ़ रहे हैं तो पहले टर्मिनल आयेगे VThevenin = 0 इसका मतलब है कि , -20 और V = -80 = VThevenin; इसका मतलब है, VThevenin; =-100 वोल्ट।
