Hello thanks for your help! Does that mean that when the output is 50V(as in your example), the output is "slowly fed back" to the V- input? Because I have always thought that the V- will immediately become 50V as well when the output becomes 50V. And also, does that mean that the input...

Since we assume infinite open loop voltage gain, then the Vout hence the V- is infinite too in this case??

Addition: The closed loop voltage gain i checked from the websites is this, which consists of feedback fraction, which formula is correct between this formula and the formula shown in my main post's photo?

The book says that " The op-amp multiplies the potential difference between V+ and V- by the open-loop voltage gain to produce Vout." So my first question is, since we say we assume open-loop voltage gain is infinite, so does that mean the Vout produce will be infinite too? Then, the book says...

We say that there are three ways an emf can be induced: a) changing the magnetic flux density B b) changing the area A of the circuit c) changing the angle Can I know which of the category above is moving the wire/current-carrying conductor across the magnetic field belong to? Why?

Hello. Thank you for your reply! I understand the formula you derived, but still can't understand the meaning of "change in area" mentioned in my photo attached. Is there any change in area when the conductor is moving across the magnetic field? Does the "change in area" causes any change in...

Can anyone explain the above answer to me? What does the "change in area" mean?
