Non Ideal Vs Ideal Op Amp Circuit

[@haripatel47]

Thanks a lot for this video, it helped me a lot

[@samkelodlamini6909]

Is it always given in the question if the Op Amp is ideal or Non-ideal or is there a way to tell if it is ideal?

[@Lukas-mq3vv]

usually assumed ideal and given if not

IMPORTANT: A novice might confuse for NON-ideal amp Ao (A_open_loop) with Af (A_feedback) = -2k/1k = -2
in the case shown above Ao =1,000 Af = 2k/1K =2
Vin = +1v , Vo = -1.944v so e(-) =0.006v; e(+) = 0v (Gnd)
