jb RC Unit Capacitors Application

Do you hear about RC unit Capacitor? A kind of components which installed by a capacitor and a resistor as a unit.

So why do need to make such type of component? It’s quite common for us to see the resistor and capacitor is used in one circuit,
RC circuits are really cool because instead of a steady flow of current, an RC circuit is one in which the current varies over time.
If you ride your bike to work or school you know that you'll be safer when you wear a helmet with a flashing light on it. 
But what you may not know is that the light flashes because of an RC circuit! 
The duration of the flash is determined by the resistance and the capacitance in that circuit. 
For example, a small capacitance would produce a quicker flash, whereas a larger capacitance would produce a slower flash.
