AI Thread Summary
The discussion revolves around solving for the equivalent resistance (R_eq) between terminals in a circuit involving resistors. The user initially struggles to understand how to calculate R_eq, believing that 24 ohms and 12 ohms are in parallel, followed by a series connection with a 22-ohm resistor. After some confusion and time spent on the problem, the user eventually finds the solution, confirming that R_eq is indeed 30 ohms. The thread highlights common challenges in circuit analysis and the importance of understanding parallel and series resistor combinations.

Hey everyone..I am new to this forum(2nd time I post a thread)

I have this exercice,which I am unable to solve..it has been 1 hour

Determine Req between terminals ab in the figure above



The figure is in the attachement..

In the solution ,they say that Req =30 ohms..but i am not getting this answer..

This is how i am reasoning:

24 and 12 are in parallel

then (24 and 12) with 22 are in series..
but then what next?

thank you
