| - | A varistor is a resistor where the value of the resistance varies depending on how much voltage is applied to it. I have no method or resources for testing these yet. | ||

| - | These components are very frustrating to identity because they often are almost identical to some dipped ceramic capacitors. And information for differentiating the marking is few and far between. So here is one site at least that helps teach you how to [[http://epicbeardquest.blogspot.com/2015/03/is-that-varistor-or-capacitor.html | identify the different markings between a varistor and a capacitor]]. | ||
