From your question it sounds like alternating current.
Alternating current would fit this description.
It is called an alternating current
There is two types of current. Direct current and alternant current. The one running in only one direction is Direct current.
Electrons do not flow, but they might be though of as 'flowing' as they transfer charges between them. The reason that electron flow is the opposite direction from current is that historical theories of electrical flow (current) treated it as a movement of positive charges rather than negative charges.There is no actual difference that could be discerned, except that we now know that negative charges (electrons) constitute the basis of most common electricity.
Current i.e.rate of flow of charge when stops flowing in a circuit then fuse does not blows out. The only work of fuse is to blow away when the current starts flowing greater in magnitude than the rated current value.

Polarity
. . . then that would be alternating current, or simply, 'AC'.

This is known as DC. Direct Current.

the charge of the electron is negative
Current flowing in only one direction.
Direct current (DC) is nothing but an electric current flowing only in one direction.
An electric current flowing through a circuit causes a magnetic field. This is due to the movement of electric charges, usually electrons, in the circuit. The magnetic field produced is perpendicular to the direction of the current flow.
