一(yi)、如何辨別強弱(ruo)電(dian)(dian)？1.強電(dian)(dian)傳導(dao)的是(shi)電(dian)(dian)能，而弱(ruo)電(dian)(dian)傳導(dao)的是(shi)信(xin)號。如電(dian)(dian)動剃須(xu)刀、手電(dian)(dian)筒等(deng)傳導(dao)的就是(shi)電(dian)(dian)能，屬于強電(dian)(dian)類，若僅因(yin)其(qi)電(dian)(dian)源為兩節(jie)干電(dian)(dian)池、電(dian)(dian)壓較小，就將其(qi)判定(ding)為弱(ruo)電(dian)(dian)是(shi)非常不(bu)正確的。2.高壓包(bao)括強電(dian)(dian)，強電(dian)(dian)不(bu)一(yi)定(ding)屬于高壓;低壓包(bao)括弱(ruo)電(dian)(dian)，弱(ruo)電(dian)(dian)一(yi)定(ding)...
