kya isko 9v ki jaga 12 pe chala sakte hai kya

Good idea. Simple but usefull....👍 If we want to change delay_duration, which one should replace.... resistor or capasitor?

Cap

@@wibowoims527 Yeah, just use a baseline resistor like 1k or like 10 ohm. Then record the time on a graph then you can calculate the amount of capacitance required for a specific time. That’s how I fixed my air conditioner.

Used a 2n3904 and switched it around to work right (is opposite than bc547). Used a 9v source and fucker blew its lid... thought 2n3904 handled bigger loads than bc... but your circuit is not right, i had to run wire from switch to pin connecting npn to relay..
