DescriptionDelay circuits are used to protect electronic circuits from abrupt changes in power. These circuits introduce some finite delay before the device gets turned on. The most simple way to implement these Delay switch circuits is by using capacitors.
In this Delay switch using RC circuit, we can see that if we turn on the DC power by closing the switch S1, both the capacitors start charging. It means that as long as they keep charging, no current or little current passes through the LED D1. As soon as the capacitors get fully charged, no dc current can flow through them(as per capacitor’s property) and now all the power appears across the LED and R1. Two capacitors are used here to increase the charging time hence increasing the delay.

Interesting for kids, help them understand about rc circuit.
Good introductory tool for an advanced technology
It is very basic.. however an excellent way to introduce and teach kids about RC Circuit.
