My question is about differential amplifier. I don`t know \$2\frac{\Delta R}{R}\$ proof.
I don't know this proof. Why \$Av(cm) = 2 \frac{\Delta R}{R}\$?
This is my solution.

Sounds like a homework question. Have you tried to solve this yourself? Please show us your work so far. – Elliot Alderson Apr 26 '23 at 14:46

It's not a homework. I thought it was easy, so I did it myself, but it was harder than I thought, so I asked – SDG Apr 26 '23 at 15:38

Is there a definition of $\Delta R$? – electroGeek Apr 27 '23 at 05:02
