hi,
I need a little help regarding formation of a small circuit. I have a 12 volt battery and a 5mm led diode. I just want to check forward and reverse bias test. For that purpose I use breadboard and mount a diode ,resistor and 5mm led diode (all connected with battery) .The test works fine but the thing which is confusing me that when I connect it with a battery then in what order first should I mount

1- (a) Resistor , (b) diode , (c) 5mm led diode
or
2- (a) Diode , (b) resistor , (c) 5mm led diode

Which formation is technically batter.

Thanks.

 

hi g,
Welcome to AAC.
As the battery is 12V DC, what is the purpose of the diode in series with Resistor and LED.?

Thanks for your reply. I am beginner in it. The porpose of diode is only just to experiment forward and reverse bias test .
If I unmounted the diode my circuit even works . I just want to know the current formation for own experiment of my breadboard.

 

hi,
I usually have the resistor connected to the +Vsupply and the LED to 0V.
I would advise not to apply 12V DC reverse voltage to your LED.
The reverse breakdown voltage can be as low as approx 5V depending on LED type.

The physicsl sequence does not matter as long as they are all in series

 

Thanks for guiding me. Appreciate it.
