Question

explain what happens when an electric current passed through uranium

Answer 1

it can burn and give energy

Answer 2

Radioactive metals like Uranium are known to be bad conductors of heat. When an electric current is passed, the flow occurs only in the outer electron shells of an atom. Therefore, there might not be any big difference either in the radioactivity or in the half-life of the element.

 

Although the electric field could make a difference, the nuclear force of the radioactive metals is stronger than the electromagnetic forces.
