a material or device that conducts or transmits heat, electricity, or sound, especially when regarded in terms of its capacity to do this.

a solid substance that has a conductivity between that of an insulator and that of most metals, either due to the addition of an impurity or because of temperature effects. Devices made of semiconductors, notably silicon, are essential components of most electronic circuits.

semiconductors are in a lot of toys that need a low amount of energy ,but the only way to achieve that is by using semiconductor

these are found inside of multiple things like computers or phones.


An electrical insulator is a material whose internal electric charges do not flow freely, and therefore make it nearly impossible to conduct an electric current under the influence of an electric field.

we find insulators when we're walking, in the car, or looking out your window from your room.



these are all alike because they serve the same purpose, resisting energy. They all deliver different amounts of energy for different uses.


some limit way more than an object would need. These do not look the same for one cause that is how much energy they resist.
