Electric Current: Electric current is simply the flow of electric charge. In solid conductors the flow of electrons and in fluids the flow of ions as well as electrons constitutes the current. An electromotive force (emf), provided by a cell of a generator, is essential to maintain a continuous flow of current in a circuit.
Electrical Resistance: When electric current flows through a conductor, e.g. a metallic wire, it offers some obstruction to the current. This obstruction offered by the wire is called its electrical resistance. The resistance (R) of a wire of a given material depends on its length (l) and the area of cross section (a)
R = ρl / a
If the wire has a circular cross section of radius r, then a = ∏ r. Thus,
R = ρl / ∏ r
ρ is a constant called the resistivity of the material of the wire. Resistivity of a good conductor (e.g. copper, silver, etc) increases with temperature, whereas, resistivity of a semiconductor (e.g. carbon) decreases with increasing temperature.
Resistance is device energy loss
All I know is Electrical Resistance is measured in ohms.
