二极管在电路中应用是怎样的呢？

Updated: 2022-03-17
Views: 5200

二极管是一种不对称的电子元器件，也就是只允许一个方向流通，所以这种单向导电的特点在整流电路中用起来还是比较多的。测量好话也非常的简单，也就是通过万用表的电阻档就可以直接测量。因为两次测量如果有一次有显示数据的话说明是正常的，如果两次反复测量都没有数值显示，说明已经断了。如果是发光二极管的话，通过测量二极管就会发光，所以……

Views: 5167

MOS管也是一种半导体，并且这样的器件被称之为对称的，并且因为比较常见，体积也比较小，所以在很多地方能够代替双极型晶体。虽然也属于长效应管，可是也是一种控制的电子元器件，看起来很像三极管，实际上原理是截然不同，在开关电路中也是经常的使用，主要是根据电位来进行工作的。 MOS管作用还是非常明显，不仅仅用于放大镜，而且在使用的时候不用使用电机电容，毕竟自身阻抗还是很高的，另外在面对很多级的放大电路的时候，效果还是非常不错。并且不仅可以做电子开关，而且还可以做可变电阻，所以使用效果还是非常的明显。 MO
