It is called an alternating current
That would be alternating current or 'AC'.
Alternating current would fit this description.
From your question it sounds like 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.

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.
Strictly speaking, it's energy flow that has direction -the term 'power' merely describes the rate at which that energy is flowing. Having said that, however, the term 'power flow' is indeed used, but it must be understood that the term is really describing the 'rate at which energy is flowing'. There is no direct relationship between the direction of current and the direction of 'power'. For example, an alternating current is continually changing direction, while the resulting power flow acts continuously in the same direction. The reason for this is that current flow direction cannot be taken in isolation, as it must be considered together with the direction of the potential difference that is causing that current to flow. If we allocate positive and negative symbols to specify the direction of potential difference and current, where (for example) 'positive' defines a clockwise direction around the circuit, then the product of the two positive signs result in a positive direction for power flow direction. If we now reverse the direction of the potential difference and the current, their signs both become negative, and the product of two negatives is a positive -indicating that the power does not reverse direction, but continues in the same direction.
