node branch loop

What is node ?

               When two or more branches  are connected at a point then that point is called a node.
               


                  EXAMPLE :

What is branch ?
                              
                   A single element with its terminals is usually called a branch .( resistor,voltage and etc. )


What is loop ? 
                             

        

          is any closed path in a circuit. 

      

kirchhoff's current law :


               states that the algebraic sum of currents entering a node or a closed boundary is zero.

                 
               EXAMPLE :
                     
                        

                         
                  The current entering = current leaving  junction.  



kirchhoff's VOLTAGE law :  

                   states that the algebraic sum of all voltages around a closed path or loop is zero.

                         
                   EXAMPLE : 

                           
                       
                    
                                        

                                                       LEARNINGS :


                 In this topics i learned a lot  including how to identify a branch, nodes and loops in a circuit . then in( kcl) the current entering is equal to current leaving junction otherwise (kvl)
states that all voltages around a closed path is equal to zero .
