Conductors, Insulators and Semiconductors
What is a Conductor?
A conductor is an object or material that can allow the flow of electricity, light, sound or heat with minimum resistance. One of its example is the pan.
The pan is made of stainless steel. In this case, the heat can easily flow in the pan. The heat can transfer from the pan to the food it contains.
What is an Insulator?
An insulator does not allow heat, electricity, light, or sound to pass through it. Air, cloth and rubber are good electrical insulators while feathers and wool make good thermal insulators. Another example of insulator is the plastic ladle.
The ladle or scoop is made of plastic. It doesn't allow electricity,light, etc. to pass through. So, when we are cooking we will not get burned for it is an insulator.
What is a Semiconductor?
A semiconductor is a material which conducts electricity more than an insulator but less than a pure conductor, such as copper and aluminum. Semiconductors are usually very small and complex devices. Another example is the pot with plastic handle.
The pot is made of steel and its handle is made of plastic. It is useful for we will not get burned while holding it even when it is hot and even we don't have mittens or pot holder.
