Electric current is the flow of particles with:

Electric current is the flow of particles with either positive or negative charge depending on the materials.
 

In the flow of electricity, a point on a conductor or element with high potential is considered positive. In contrast, a point on a conductor or element with a low potential is considered harmful.
 

Electric current flow is said to be analogous to the movement of water. Electric current moves from high to low levels as water does.
