Hi there,

You need to project and draw an electronic circuit to stabilize it on 3.3V voltage of 5 resistors with different summers. Resistance values should be taken from the 5 numbers from below.

41474

So, for example 4 is the first number so first resistance should be 4 kΩ the second number is 1 and the second resistance should be 1kΩ , the third number is 4 and the resistance should be 4 KΩ and so on.

Resistances can be connected in any form and can use various electrical and electronic components, the goal is to stabilize the voltage at each resistance in 3.3V where the resistance of the source is 2 kΩ.

You can set the source value yourself and the circuit must have + or - 20% voltage tolerance. In the end you need to calculate the power of the source which is needed to stabilize the tension of all resistors.

Let me know if anyone of electronics or electrical engineering have the ability to complete this project.

No, I don't; but apparently, you do. Is this homework / school work?

What do you mean by various electrical and electronic components?

Do you mean you can use op-amp and BJT?

It's pretty hard to tell just what is being asked for. I suspect it is mostly a "english as second language" issue and, if so, we should be able to work through it.

But this is pretty clearly some kind of coursework and, as such, YOU need to do the bulk of the work. Don't challenge other people to do your homework for you.

Show you best attempt to solve, or at least get started, on the problem. This will not only help us figure out where you might be going astray and help you get back on course, but in this case it will probably go a long way toward letting us figure out exactly what the problem is in the first place?

What do you mean by "5 resistors with different summers"? What is a "summer" in this context?

Is this correct?
3.3V over each resistor(s).
Resistors are all connected in a network.
Requested: how are they connected and what is the voltage of the power source?
all parallel @ 3.3V is correct but considered as wrong answer.
