Electric current 
.
.Its SI unit is ampere (A).
The conventional direction of electric current is the direction of motion of positive charge.
The current is the same for all cross-sections of a conductor of non-uniform cross-section. Similar to the water flow, charge flows faster where the conductor is smaller in cross-section and slower where the conductor is larger in cross-section, so that charge rate remains unchanged.
If a charge revolves in a circle ...
