The correct answer to this question is Its a path that lets electricity that does not let electricity pass through it well. In most instances, one wants to trap the heat and to slow down the flow. We also want to stop the flow to help prevent electric shocks.
There are many types of insulators around us every day, including wood, plastic, and ceramics. An example is a kitchen utensil like a spoon. The spoon is an insulator because it prevents the heat from the pan to spread to the hands. The wires of electrical appliances are also insulators so that the heat from the pan won't pass to the wires.
