Can someone explain to me. in a circuit when the voltages are the same what are differents? the current or the restistance?

Question

For lumped circuit analysis (low frequency), a resistor's resistance will not change.  The material properties of the resistor determines its resistance, not current or voltage.  So a 2.5 ohm resistor will always be 2.5 ohms.  Therefore according to Ohm's Law, a change in voltage will cause a change in current (and vise versa).

I re-read your question.  Are you asking about solving a circuit's parameters with several elements?
