## Main Question or Discussion Point

In this part , m doubtful about finding equivalent resisitance and thevenin's resistance (Rth)..

m giving a circuit in whi there we have to find current through 4 ohm resistancce connected acreoss terminals A& B.., on left side of A, B there is a battery of 8V and a resitance of 2 ohm in series with at & on right side of A,B there is a battery of 12 V and resitance 2 ohm in series with it..

for finding out thevenin's resitance , the 2 resiitances both 2 ohm are taken as parallel... so Rth=1ohm

but for finding out the total current in the circuit the 2 resitances are taken in series..!!

this thng is making me reallt doubtful... I understand finding the equivalent resistance but why for thevenin resitance the resistances were taken as partallel.. its a short example but the are more complex ones..which m 'nt getting due to ths..plzz explain it..!!
