THE CORRECT USE OF...

1. Resistors

   • They limit the current flow in a circuit
     • Prevent possible damage by the amount of voltage
       • Types
         • Fixed Resistors
           • Has a resistance already determined
             • No change
             • Carbon film
             • Metal Oxide Film
             • Wire wound type
         • Variable resistors
           • Change resistance, it is not defined
             • The most common has leads
               • Source
               • Output
               • Ground
       • Example
         • Led circuit
       • Correct use

2. Capacitors

   • Store electric charge for short time
     • Structure
       • Two conductors
         • Separated by an dielectric insulator
     • Have equal and opposite charges
     • Can be modified from its conductivity and the size of its dielectric
     • The more area, the more capacity
     • Types
       • Ceramic Disc Capacitor
         • Versatile and made for lower voltage
       • Electrolytic capacitor
         • Polarized
         • Higher capacitance
     • Correct use

3. Diodes

   • Limit the flow of current to one direction, never to the other
     • Funtional factors
       • Manage the current flow that is going to pass through the circuit
       • Prevents voltage coming in the opposite direction
     • Types
       • PN Junction Diode
         • Rectify currents
       • Light Emitting Diode
         • LEDs designed to illuminate
     • Correct use

4. Transistors

   • Are used as a switch or an amplifier
     • Types
       • NPN Transistor
         • Parts
           • Base pin
           • Collector pin
           • Emitter pin
     • Can be at conductive or non conductive state
     • Practical use
       • They are very fast
         • For quick systems
     • Correct use
