Current-resistance analysis

[REEEEEEEE]

Homework Statement

Graphically represent in EXCEL or equivalent program the characteristics
current-resistance (abscissa) of the three currents in the circuit. Comment the obtained graphic.
(Hint: Plot the theoretical, simulated and experimental characteristics and compare the
differences between values and their evolution).

Relevant Equations

U=RI (OHM'S LAW)

For example given the circuit

I make the graphs :

and comment that or graph 1 as resistance grows larger the current grows smaller (is inversely proportional) I will use the simulation and experimental data to check the values and conclude that this act is true.
Is this what I'm supposed to do?

Those are odd-looking graphs. Where do those numbers come from? Which branch(es) of the circuit do the graphs refer to? What is being varied and what is constant? (e.g. if you are plotting the current through R2 as R2 varies, is R held constant? At what value? This is important, though the question as quoted doesn't make it clear.)

Above the graph you can se the values o current and resistance and I apologise or not explaining that the order goes rom top to botom:R1,R2,R.

But that is meaningless. Each set of values {R1, R2, R} will be associated with a particular value of the current - or, to be precise, with a particular set of values {I_R1, I_R2, I_R}. What you need to do is graph one of these current values as a function of one of the resistances, e.g. I_R vs. R while holding R1 and R2 constant. And do this in turn for each of the 3 currents.

This ^^^.
Can you post the complete question? Maybe post a (good) picture with your phone?
What component values are fixed, and which are varied in the analysis?
