Symmetric circuit

1. Outline
   1. Junior high school curricular simply comprise an electrical circuit, i.e. only a single series of parallel relationship, there is no circuit loop. But in fact most of the circuit does not have this nature, most of the circuit by the secondary level equivalent transformation can be converted back to a symmetric circuit a simple circuit.

      name is I made it up, a professional scientific name
      
      1. Axisymmetric circuit
      2. Centrosymmetric circuit
2. Axisymmetric circuit
   1. Decision
      1. Such circuits are called generic having inverted symmetrical nature of the network, i.e., the axis of a two circuits are equivalent, by flanging may coincide
         FIG., The entire network on the linear axisymmetric $ A $, it is axisymmetric circuit

   2. nature

      1. For axisymmetric circuit, we will not become an open cross section, the cross section shorting
         

   3. application
      1. 

          

3. Centrosymmetric circuit
   1. Decision
      1. If a circuit is symmetrical about a center point, i.e. part of the network at a point of rotation about $ 180 ^ {\ circ} $ coincides with another part, called this network circuit is symmetrical
