that transmits the input after a fixed timeCan sum1 plzzzz xplain wat on earth a tym delay circuit is????
thnx but i need a detailed xplanation. hw it works n all datthat transmits the input after a fixed time
its gonna drop lowwhat do you think about the threshold for this paper?
Chucky plz help me. cn u xplain wat a tym delay circuit is in detail???I did it, and it was okay, not the best paper.
Checked out the answers with buddies of mine, and I seem to have got my answers correct, just worried that I didn't do the explanations all too well.

what was the bird question aboutgotta admit the bird one was very hard.
the bulb was 6did anyone did the bulb thing
Oh Allah, plzz help us!I hope varient 1 would be Easy
The Time Delay circuit is directly connected to the AC lines to derive power to the components. Resistor R1 drops AC voltage and D1 rectifies the same to give low volt DC. The high value capacitor C1 act as a smoothing capacitor as well as the time delay device. That is the SCR conducts only after C1 is fully charged. It takes around 2 minutes. When C1 charges fully gate of SCR gets firing pulse and it conducts. This charges C2 which also give another one minute to fire the Triac trough R3. When the triac conducts, AC load gets electrical continuity and turns on. Capacitor C3 keeps the voltage level at the gate of triac and eliminates the back lash effect.Oh Allah, plzz help us!
