在放大器的功率输出里，在放大的过程中，它随着输入控制电压的变化而变化。其内阻特性如何？我们可以按照晶体管的内阻来设计，也就是发挥它的极限能力，但用那些方法测内阻呢？（设电源的内阻为0）。非常感谢！

[s:247] 很郁闷有点想不通.电阻1000R.二极管下面的电源电压为3V..当左边输入小于3V时.右边输出电压为0.当左边输入电压高于三V时输出电压为3V.也就是所谓的恒压特性...我不明白的地方...

这里的爱好者```有很多像我这样的菜鸟``会问一下让大侠们觉得弱智的问题 ``大侠苦恼``菜鸟一样苦恼。那么菜鸟们来学习这些吧```可以让你很快入门初级电子电路知识，掌握了这些东西然后再灵活运用变通，...
