The Dark Days is a term commonly used to describe the collapse of the first rebellion in Panem, which occurred 74 years prior to the beginning of the series.When the rebellion started going badly, District 13 abandoned the other districts to win freedom.ost important for the people of 13, it was the center of the Capitol's nuclear weapons development program. During the Dark Days, The rebels in 13 wrested control from the government forces, trained their nuclear missiles on the Capitol, and then struck a bargain: They would play dead in exchange for being left along.
A resistor is a little package of resistance: wire it into a circuit and you reduce the current by a precise amount. From the outside, all resistors look more or less the same. As you can see in the top photo on this page, a resistor is a short, worm-like component with colored stripes on the side.
Resistor sources are considered to be the simplest forms of current source. They involve a circuit that contains a resistor in series with a source of voltage. The current generated from this system is equivalent to the amplitude of the voltage, divided by the resistance of the resistor. A resistor current source is generally not considered effective on its own because of the large amount of power lost in the resister, but many types of current source use elements of this setup. For example, active current sources often substitute a different element for the resistor.
