- NO AI. Thank Youarrow_forwardPlease solve in detailarrow_forwardHere the Req is 8 my prof solved it and got R3 is parallel to R4 in series with R2 and this combination is parallel to R1. i don't understand how he got these relationships. initially i did the opposite i took (R1//R4 + R2 ) + R3 but got the wrong answer why is it wrong? can you explain to me if there's a trick i can do to understand these questions better and know the configurations of the resistors in a better manner?arrow_forward
