How Do Double Insulated Tools Work?
One of the biggest dangers facing anyone using electric tools is electric shock. In the past, the only option available to users was a three-prong plug—a standardized plug with two flat prongs and a third round “peg” that grounded the tool when plugged into a properly-wired three-prong outlet. Modern electric tool manufacturers have given us another option which can be plugged into a standard two-prong outlet; these are called double-insulated tools.

Due to their low resistance, the current drawn through them can easily exceed their maximum capacity and they will burn up. A resistor, an electronic component that limits the amount of current that can flow through it, can be placed externally in series with an LED to protect it from c
