resistance(電阻):
every thing have resistance, it can defined as:
(p.d.=potential difference)
p.d. across conductor
resistance(電阻)= -------------------------------------
current thought conductor

current(電流):
current is the rate of charge flowing in a circuit, also when the ends of the metal are connected to a battery, the negatively-charged free electrons move towards the positive end.this drift of electrons gives an electric current.

when a circuit has current it must has resistance
a conductor has a resistance of 1 ohm if a current of 1A flows through it when a p.d. of 1V is applied across its ends.

Resistance is a material property which inhibit the flow of electric current through the material.
Current is the flow of electric charges in a unit time.
For a given voltage, the higher the resistance, the more difficult is the flow of current through it. In contrast, a lower resistance permits larger current to flow through.
The two quantities are related by the "Ohm's Law", which states that at a given temperature and voltage, the current flows through a (conducting) material is inversely proportional to the resistance of that material.

Resistance Is A Force To Resisting Current In A Complete Circuit,
Or You Can Say Resistance Can Make The Current Flows
Current Is The Movement Of Electrons,Current Produces By Complete Circuit,Voltage,And Resistance,The High Potential Flow To The Low Potential Via The Loading.

resistance系電阻..current系電流

兩者在電學中都是非常常見的。電阻可令電流消耗。
