hi, could you tell me why you want to add additional capacitors?Hello
I don't have an electrical or electronics engineering but i know some basics about electronic
I'm trying to build a thermostat please help
i want to add capacitors on this diagram, can you tell me where and why please
That sounds a little difficult to respond to because you are literally saying that you want to add something and you are asking how and why.i want to add capacitors on this diagram, can you tell me where and why please
i should say : I want to add or remove capacitors on this diagram, can you tell me where and why please !?hi, could you tell me why you want to add additional capacitors?
Without more information, I can only suggest that you print out the schematic tape some colorful capacitors to each corner.
yes it is heater resistorhe parts in the circle are resistors, are these what you mean?
You will get a better response if you provide more information.....where did that schematic come from? Why do you think you need to add capacitors? Homework assignment or what?
And non-existentThe capacitors on the drawing are all 100uF, and they all connect to the same point, this might seem confusing.
It is however where they are positioned that is important, each capacitor decouples a section of the circuit, and should be placed close to that section of the circuit.
This is because of the pcb tracks & wiring resistance affecting the circuit.
You can replace a electro with a non electro so long as the voltage ratings etc are the same, although for 100uF a non electro would be very large.
i want to replace the PNP Tr by NPN Tr (red cercle)Why the voltage divider?
What do you mean "big"? High value resistors are generally very small in physical size (or the same physical size as any other resistor) because very few amps can get through them so very little wattage. I've never heard of anyone being concerned with using high-value resistors when a high value resistor is perfectly suited (needed) for the circuit.Hello lec_t
thank you very mutch
i want to replace the PNP Tr by NPN Tr (red cercle)
i don't know , i think that it would be better with the NPN , also by the voltage divider ,i can have good control for the NPN Tr ! ?

but please i want from you to give me another way to do this :
on my old diagram the hysteresis was done by big resistor (red ligne)
please are there any other method for this (for example a voltage divider ) because i don't like to use a this big resistor

The 'big' resistor is the same physical size as the other resistors. What is your objection to its use? This is the usual and simplest way to provide hysteresis.i don't like to use a this big resistor
The professor said his design must have at least 10 components? (Just guessing)You seem to be obsessed with voltage-dividers . Yes, your latest PNP versions will work with a voltage-divider, but what advantage do you think it provides? I see it as an unecessary complication rather than an advantage.
