Originally, there were thirteen districts in Panem. During the Dark Days, the 13th district was obliterated by the Capitol and is no longer recognized as operational. Each District provides something different to the Capitol; for example, District 12 provides coal and District 4 provides fishing.uring the Dark Days, the 13th district was obliterated by the Capitol and is no longer recognized as operational.

A resistor is a passive electrical component with the primary function to limit the flow of electric current. The resistor is a passive electrical component to create resistance in the flow of electric current. In almost all electrical networks and electronic circuits they can be found.
  The trimmer resistor is a calibration device used to correct (trim) the resistance of some other resistor.   An example might be the feedback loop of an op-amp in com â¦ mon mode. If you wanted a gain of two, you might use a resistor divider with a two to one ratio.
