How to find the differential equation of the current i₁?
I am trying to find the differential equation of this circuit:
I tried to use KVL at the left mesh which gave me
\$E=R\cdot i+V_c\$
From \$V_c\$ I can calculate \$i_1\$, but then I didn't know how to ...

What's the performance difference between these two differential amplifiers?
Both of the below circuits are sinking 1A of current.The TL074 has a slew rate of 13V/us and OP07 0.3V/us. Does that makes the upper circuit have s slower response time?
What other differences, ...
