- - - - Is open when the energy of the power source cannot reach the load devices, so the electric current cannot flow.
    - - Is closed when the energy of the power source reaches the load devics, so the electric current flows
  - - - Voltage: This is the different in the charge between two points, ( Positive and negative terminal), which makes the electron move
        
        Symbol: V Unit: Volt
      - Resistance: This is the opposition to the flow of the electric current. It unit of measurement in the International System is the ohm
        
        Symbol: R Unit: Ohm
      - Current: This is the intensity of the current or the amount of electrons flowing through a conductor over a certain time.
        
        Symbol: I Unit: Ampere
- - - - Many power stations have a impact on our environment.
        
        The use of renewable energies is being promoted as a green alternative to conventional power stations.
- - - - The Ohm's Law says that the current in a circuit is directly proportional to the electrical potential difference impressed across its ends and inversely proportional to the total resistance offered by the external circuit.
        
        To came up this law we need to do a equation relating the three variables.
        
        The variables that came up this law are:
        
        The votage.
        
        The unit of measure is the volt.
        
        The resistance.
        
        The unit of measure is the Ohm.
        
        The current.
        
        The unit of measure is the Ampere.
