Hey guys, I just wanna ask you about problem 4.101 in Electric Circuits 9e by Nilsson and Riedel. I'm confused on how to simplify the two pairs of parallel resistors (1Ω||3Ω and 2Ω||4Ω). How should I connect the equivalent resistors? What should I do with the wire between them? Please explain it to me as clearly as you can. Sorry if I can't provide you an image of the problem. Thank you in advance.
