Electric Current

In physics we learned about electric current, resistance and conductivity. Electric current is the flow of positive electric charge and the units are amperes (A) which is equal to one coulomb per second. To find the electric current you divide coulombs by the time. An example to find the electric current is when you are given 3000 coulombs and .2 seconds. Divide 3000 by .2 and you would get 15000 amperes. Conductivity is how well a material conveys electric charge. Conductivity depends on the number of free electric charges available to move and also the mobility of charges. Resistivity is how well something impedes the electric charge.
