sentence: Most resistors used in electronics today are carbon resistors.
sentences_before: There are many different types of resistors you can find. They are all made with a resistance material encased in a non-conductive material casing, such as plastic. Fixed resistors are usually made of carbon encased in  a plastic cylinder, with a connecting wire on either end.
sentences_after: Older resistors were made of a poorly conducting metal, in order to restrict the flow of electricity.
