By doing more in-depth assessment of conceptual knowledge related to the movement of free electrons on an on-menrus, you will be able to meperjelas meaning of electric current. When we talk about the electricity in our shadow is the movement or displacement of free electrons (electron current) continuously. For practical purposes, the flow of electrons movement commonly known as electrical current, but with the agreement that the direction of the electron flow direction of the movement of electrons, while the electric current direction opposite to the direction of flow of electrons, are like shown in Fig 1:14.
Figure 1:14 electron flow and electric current
To generate a powerful electric current or beneficial as we feel in our daily lives, it must be produced electron flow constant and continuous.
Electron transfer can occur in several ways, but the most important is in three ways, namely friction, chemical, and magnetic induction. How to friction will cause electrostatic forces, chemical way to produce electricity on batteries / accumulators, and how the magnetic induction generates electricity in a generator.
