Relay OFF Time delay timer by using NPN Transistor and Capacitor

This video how to make Relay OFF time delay timer by using NPN transistor and Capacitor, first of (B)base touch to positive voltage so the capacitor also gets charged fully, remove to wire through the power to the base gets disconnected, the transistor continues to conduct with the aid of the stored energy in the capacitor which now starts discharging its stored charge via the transistor.The Relay also stays switched ON until the capacitor gets fully discharged. The value of the capacitor determines the time delay or for how long the transistor stays in the conducting mode.
