Rifacendo bene i conti mi trovo con il risultato , scrivo per completezza, magari può servire a qualcun altro.

La resistenza equivalente è quindiReq_th=137,5ohm

Nel circuito a destra , riattivando E al posto del CC ed usando il partitore di tensione ottengo cheE_0 è:

quindi

E i problemi quali sarebbero?

Salve a tutti, sto avendo dei problemi con questo esercizio.

Utilizzando il teorema di Thévenin calcolare la corrente i5.
Risultato = -18mA

E= 12V ; R_1=R_3=200ohm; R_2=600ohm ; R_4=R_5=400ohm


Sorgente FidoCadJ | Ingrandisci | Cos'è Fidocad



Spegnendo E ed eliminando R_5 ottengo:


Sorgente FidoCadJ | Ingrandisci | Cos'è Fidocad



Nel circuito a sinistra ho una stella che ho trasformato a destra in un triangolo dove

[unparseable or potentially dangerous latex formula]
[unparseable or potentially dangerous latex formula]

Ora essendo R_12 in parallelo con un CC posso eliminarlo e quindi ottenere Req_Th=R_1//R_13//R_23?


Grazie!
