First of all, thank you for the very quick response... I have labeled the resistors... Now, how can I find the equivalent one.
P.S. The answer is 3 ohms.
Hi! I have been trying to understand how a "complicated" circiut can be transformed to show which resistors are connected in series and which are parallel... Sometimes I manage to do it but it's often too hard for me because I can't find any sort of algorithm about it. Could anybody show me...
