A wire diameter of 0.35 means that the wire’s cross-sectional area is twice as large as that of a wire with a diameter of 0.25 mm. How does the resistance of a wire change if its cross-sectional area is doubled? Which two measurements must you evaluate in order to obtain the answer to this question?

-
The greater the cross sectional area, the lesser the resistance.

To prove it, you need to measure current (I) and voltage (V) of each wire.

To find resistance of each wire, just take V/I
