Question

what is the relation between charge and current

Answer 1

flow of charge is opposite to the flow of current

Answer 2

Current is measured in amperes, which is an SI Base Unit, defined in terms of the force (expressed in newtons) between two, parallel, current-carrying conductors. Current is the rate at which electric charge flows. Electric charge is measured in coulombs, which is an SI Derived Unit, defined in terms of current and time the ampere and the second.
