Can you complete the sentence?
_______ is used to isolate the flow of current by preventing direct contact between conductors and their environment.

The answer to this is “Insulation.” People have already noticed that insulation is one of the things that they should do for certain processes. For example, they would need to insulate their home to make sure that the temperature will remain constant inside the house even when the temperature outside is a bit extreme.

During the summer, people may want to use their HVAC. This can provide the coolness that people need so that they can stay comfortable. Through proper insulation, it will take longer for the warm air to enter the home, which means that people can stay comfortable for a longer period of time. Basically, insulation can be used to maintain the temperature of certain places or objects.
