The flow of charge is called the current and it is the rate at which electric charges pass though a conductor. The charged particle can be either positive or negative. ... "At any junction point in an electric circuit, the total electric current into the junction is equal to the total electric current out."

When electrical charge passes through a conductor, electrons are in motion. This movement is of electrons is known as electric current. ... Metals conduct electric current well, Coal not as well. Glass, Porcelain and plastics practically do not conduct the electric current at all. Pure water does not conduct electricity.
