what type of materials do you need to keep charges flowing?
1. Electric currents are not just flows of electrons; they are flows of electric charge. Both protons and electrons posses exactly the same amount of 'electricity.' If either the protons *OR* the electrons flow, that flow is an electric current.o aid your understanding, imagine a large wheel. If you give it a spin, the entire wheel moves as a unit, and this is how you transmit mechanical energy almost instantly to all parts of the wheel's rim. But the wheel itself didn't move very fast. The material of the wheel is like the electrons in a wire.
