op-amp --- input voltage
Hello,
I find op-amps very fun! And I understood mostly everything I was offered to study. But here is the thing.
Why does the voltage has to be the same at the input leads?
To be more specific.
Lets say we have a inverting op-amp. And we have an imput Vin at -ive lead.
+ive lead is grounded. Why are both then at 0 potential? Why can't -ive be at Vin and +ive at 0? Whats going on there?Does this has something to do with differential amplifier ?
