• Meeting between pairs of electrons and less dense.<\/span><\/li>\n
• Among places that have a high electron density and low<\/span><\/li>\n
• Between a shortage of electrons and excess of electrons<\/span><\/li>\n<\/ul>\n

  B. Power Lines<\/strong><\/span>
  \n<\/strong> Electricity as energy can be generated from the energy of others.<\/span> Mechanical energy, chemical energy and heat energy can generate electricity.<\/span> Electricity can flow through a conducting material, but not all materials can conduct electricity.<\/span> A material having free electrons in it, such as metals, wood can conduct electricity but which do not have a free electron can not stream.<\/span> Because electricity is a form of energy that is very widely used, it is essential to understand its properties.<\/span><\/p>\n

  Conductor connecting the poles of a power source located inside the electric field.<\/span> Due to the electric field of free electrons in a conductor moving and there was a flow of electricity.<\/span> Electrical charges originating from the elements have a fixed direction, ie from pole to pole are high-potential low potential.<\/span> Being derived from the generator keep him there and nothing has changed.<\/span> The electrical current direction is still considered the flow of electricity (DC = Direct Current) and that is not fixed is often called an alternating electric current (AC = Alternating Current).<\/span><\/p>\n

  <\/div>\n

  There are two types of electric current:<\/span>
  \n o Direct current<\/span>
  \n o alternating current<\/span>
  \n<\/a>
  \n (A) Electricity flows in the same direction<\/span>
  \n (B) alternating electric current<\/span>

  • What is meant by direct current when electrons move continuously with a fixed direction while the magnitude of change Figure 1.2a.<\/span> While on alternating current, an electron moving past regularly alternating flow direction forward or backward, in Figure 1.2b forward direction depicted on the side + (above the line 0) and backward direction depicted on the side – (subscript 0).<\/span> During the electrons move forward voltage will rise and will be in a positive position, in a state of silence, the voltage will show 0 volts and when electrons move backward voltage will drop and will be in a negative position.<\/span> Usually the direct current in the world of electronics used on radio, TV, computers, calculating machines and others.<\/span><\/li>\n
  • In more complex-and-fro flow in determining some of the prices that it has, for example, the peak price, the price of RMS etc, the details are described below:<\/span><\/li>\n
  • Frequency and Wavelength<\/span><\/li>\n
  • Frequency is the number of periods in one second.<\/span> PLN has a frequency of 50 Hz, which means that in one second has 50 periods.<\/span> Frequency has a wavelength of 2.9 images with units (meters).<\/span><\/li>\n<\/ul>\n

    Wavelength is calculated based on the constant speed of light: 300,000 km \/ sec.<\/span>
