SYMBOLS

To make a proper circuit, we have to have certain knowledge of some terms, such as, whats an open or close circuit. If we see it alive we can affirm what would be an open one or close one, it´s obvious.

CLOSED CIRCUIT                                                   OPEN CIRCUIT

                          

But when we grow it to plasm what we are doing before just doing it´s much more difficult if you don´t know the symbols so today it´s what we are going to do, learning some useful symbols.

In this picture we can se the most common symbols to show if a circuit is open or closed or what type of current is passing through it.

         1)      Wires not joined.                             1) Voltage AC source

         2)      Inductor                                             2) Wires joined.  

             3)  Resistor                                             3) Switch (open)

         4)    Voltage DC source                          4) Current source

         5)     Capacitor     

                    

                                                                                       

There are more symbols that have to be taken into account, like finding the value of the bands in the resistors. This is nearly easy and this diagram shows you how to do it.
