Therefore, electrons are not tied to freely move leaves the atom and floating in space between adjacent atoms, so that these electrons are called free electrons In some types of materials, such as metal, the outer electrons of atoms easily detached from the bonds so that it can move randomly in the space between the atoms of the material due to the influence of heat energy from the room temperature.<\/span><\/p>\n

Each electron moves evenly through a conductor, individual electrons pushing each other from the base to the tip, so that all electrons move together as a group.<\/span> Electrons from the atoms of different types have different degrees of freedom to move around the nucleus.<\/span><\/p>\n

Figure 2.1 The objects around us<\/span><\/p>\n

The ability of an object either solid, liquid or gas to conduct electrical current or electrons vary.<\/span> Viewed from an object’s ability to conduct electricity, the electric material can be classified into two groups, namely:<\/span>
\n (1) conductor or conductor<\/span>
\n (2) non-conductor or insulator,<\/span><\/p>\n

Grouping of electrical material is based on the ability conductance and electrical resistance value materials.<\/span> Apart from the two types of material there is one more very fonumental materials, namely semiconductors.<\/span> In this learning activity you will learn the three types of electrical material.<\/span><\/p>\n

Conductor<\/strong><\/span>
\n The mobility of electrons in a material called electrical conductivity.<\/span> Conductivity is determined by the type of atoms in the material (the number of protons in the nucleus of each atom determine its chemical identity) and how the atoms are connected together with one another.<\/span> Material with high electron mobility (many free electrons) are called conductors, because the baban materials have high conductivity.<\/span><\/p>\n

To determine the level of conductivity, expressed with conductance values \u200b\u200bare measured in units of mho.<\/span> Conductor material that has a high conductivity, meaning the value of konduktansinya too high.<\/span> Of sure, conductivity of each conductor is different, there is a high value some are low.<\/span> The inverse of conductivity is resistansitas.<\/span> If a conductor material declared to have high conductivity, the resistance value is low, and vice versa if the conductor material otherwise has low conductivity, the high resistance value.<\/span><\/p>\n

To express the degree resistansitas a conductor material is expressed by the value of resistance measured in ohms.<\/span> Resistansitas conductor material that has low, it means having a low resistance value.<\/span> Untik practical purposes, the resistance expressed by a capital letter R, moderate conductance is expressed by the capital letter G.<\/span><\/p>\n","protected":false},"excerpt":{"rendered":"
