Delay circuits are used to protect elelctronic circuits from abrubt change in the power. These circuits introduce some finite delay before the device gets turn on .Most simple way to implement these circuits is by using capacitors. In this 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 pass through the LED D1. As soon as the cpacitors gets fully charged, no dc current can flow through them(as per capacitor's property) and now all the power appear across the LED and R1. Two capacitors are used here to increase the charging time hence increasing the delay.
