In this Electronics Basics episode we will be having a closer look at resettable fuses which I feel like not too many people know about. Traditional glass fuses are super popular and they basically "destroy" themselves when an overcurrent is flowing. Works perfectly fine, but that means you need to replace them and that can be a problem sometimes. Resettable Fuses do not have this problem, but they come with their own unique advantages and challenges. Let's find out more ;-)
