Answer:
You would say that the current of the material can be changed by adding more electrical componets. (eg, adding more cells or by changing the resistance on the variable resisitor.
Explaination:
An electric current flows when electrons move through a conductor, such as a metal wire. The moving electrons can collide with the ions in the metal. When resistance is increased in a circuit , for example by adding more electrical components , the current decreases as a result.
