Resistors R2,R3,R4 are connected in series. I'm not sure how to find the equivalent resistance of between terminals A and B, because of the short circuit. However, I suspect the answer is R1+R4 because of the short circuit. I am confused about this, can someone help me? Thanks!
EDIT: Thanks for pointing that out. My drawing is indeed incorrect. Lets say the resistor R4 which is connected in series to R2, R3 will now be called R5
