Kirchhoff's voltage law

Given a circuit, showing V total, Resistor 1 and Resistor 2 how can we prove the voltage law?

It is a matter of the voltage's loop: if it is in direction of the current, the voltages are added, if its against they are subtracted.

The law is proven when the total voltages are zero in the sum.

But if none of the values are given and we need to prove this law, how will we do it?

What is the exact question?

Minimum you'd require in addition to the resistors is a power supply (or battery) and a DVM... Then you'd sum the voltages around the loop as kallisto says.
