If you want to understand the fundamental principles of how op-amps and electric circuits work, I recommend learning the basic principles of elementary particles, electric charge, electric fields, and electromagnetic force, without diving into the mathematics behind them.

It's easier to understand analog circuits without knowing the above because you are dealing with concrete components that abstract a lot of details away from you.

What drove me down this path is when one day I asked myself what is voltage? Why do they use the water pressure example to explain it? We are familiar with V = IR but that doesn't explain what voltage is just like an apple falling on the ground doesn't explain gravitational force.

Don't be surprised if this journey takes you down to quantum mechanics.
