SUMMARY

The discussion focuses on calculating the equivalent resistance (R_eq) between terminals ab in a circuit involving resistors of 24 ohms, 12 ohms, and 22 ohms. The correct solution is established as R_eq = 30 ohms. The user initially struggled with the calculation, particularly in understanding the combination of resistors in parallel and series. Ultimately, the user successfully arrived at the correct answer after further reasoning.

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
