hello,
I am trying to understand the fundamental of op-amp. I found this link to be very interesting: courses.ece.uiuc.edu/ece486/labs/lab1/386_op_amp.pdf I would like to know why that when the output of an opamp is connected to the input, like a voltage follower, the voltage is equal to the other input. The pdf I mentionned says that the 2 input tries to be the same voltage. So if you put 5 volt in one input, you will get 5v on the other input. Looking a the basic of opamp, v2-v1, that would have an output of 0, Then one input would be zero, It does not make sense that on the same wire, there are two voltages
thanks
k
