It's clearly noticeable you know what you're talking about. Thanks!

This video really helps me to continue my studies during this lockdown period ..

I'm confused between having the input resistance to be as high as possible and choosing it to match the previous stage for max power transfer.

[saminabashir]

why output resistance in operational amplifier is necessary? and it is ground?

[follenlearning]

but why do we want such a big input resistance??
