Very good in theory explaination of OmpAmp .To the beginner , they feel you are talking Nonsense .If I teach OA ,I will use breadboard with OA ic with wirings and connecting the OUTCOME to a Oscilloscope/Multimeter/LRCmeter to display the waveform/voltage/current measurement . Or using Multisim or FRITZING software to demo the OA functionality Simulation. Let the beginner to actuallySEE/practicallyHANDSON ,then explaining in THEORY , it will be a more EFFECTIVE teaching !

隔电流，通电压
是这样吗？
运放不就是一个理想状态的大三极管吗?不知道为啥叫运算放大,应该叫等比例放大,模拟不存在运算
为什么Avo趋向于无穷大的时候极限为1了呢 没明白
因為, 之後就可以配上電阻的串聯或並聯, 依比值關係得到增益(放大倍數)的控制(設計) 了.
半天说不到正题上
希望多一些关于硬件的视频，模电数电和微机原理之类的(๐•̆ ·̭ •̆๐)
