Can you please answer my questions to my project?😢😢😢
Can you please tell how to completely stop this LEAKING CURRENT? One thing I noticed is that...
With the 2 base inputs OFF i.e. not connected to 12/5v supply, there's LEAKING CURRENT of about 50 micro amps.
Hence, these npns are still consuming current.
Can you please tell how to completely stop this LEAKING CURRENT?
What will be the values of the 2 resistors if 12v is supplied to the 2 transistors rather 5v, and also 12v to the supply side of the LED??
Because I currently have the same project...
In place of LED, I will put 12V 756 ohm resistance relay.
And in place of 2n3904, I will use BC547.
With 12V circuit I usually use at least 1,000 ohm resistors if they are 1/4W.
@@Electronzap so can I use bc547?
@@Electronzap1000 ohm or 100, 000 ohm for 12v circuit????
Because in your 5v, you use 10,000 ohm resistors.
Now, I'm confused 🤔🤔🤔
@@tnamen1307 For 12V you can up to 50k for both.
@@ElectroAtletico okay I used 40000 ohm and it's working as expected. Thanks for the information.
