In which direction electronic current flows?

There is a positively charged sphere A and negatively charged sphere B, such that they are brought in electrical contact by a copper wire.

One Line Answer

Sphere A is positively charged and sphere B is negatively charged.
Both spheres A and B are brought in electrical contact by a copper wire.

Electronic current flower from sphere B to sphere A i.e. from a body at lower potential to the body at higher potential.
