SUMMARY
A charged rod cannot possess a voltage measured in amperes (A); voltage is a measure of electric potential difference, not current. The discussion clarifies that voltage requires a difference in charge between two points, while current, measured in amperes, refers to the flow of electric charge. Additionally, the concept of "magnetic voltage" is introduced, indicating that magnets have a magnetic potential due to their poles, but this is distinct from electric voltage. The key takeaway is the differentiation between voltage and current, as well as the understanding of potential differences in both electric and magnetic contexts.
