A conductor wire has a cross-sectional area A and length I given a potential difference Va and V so that a strong current I flows as in the picture. Which one of this following statements that is true?

Select one:

The potential Va is the same as the potential V. The current density flowing in the wire is J =

The amount of resistance can be calculated using the equation R = p, where p is the type of resistance of the wire Potential Va is greater than potential V

The potential Va is the same as the potential V. The current density flowing in the AlI using the equation R=p, where p is the type
