Hi,

Ampere: A current of one ampere is constituted by the flow of one coulomb of charge per second.

Potential difference: Electric potential difference between two points in an electric circuit carrying some current is the work done to move a unit charge from one point to another. Thus, potential difference is the work done per unit charge. V =W / Q

Ohm's law: “The potential difference, V, across the ends of a given metallic wire in an electric circuit is directly proportional to the current flowing through it, provided its temperature remains the same”.
