Thread: wat is the difference between loop and mesh

some books consider them to be the same ..but this question was asked in my exam.

ysenthilece,
They are the same thing. Node equations are the other main type equation used in network analysis.

hi,
I agree with karl, basically loop can be defined as " The closed path formed by a number of circuit elements". This definition holds good even for "Mesh". So in "Network Analysis" both "Loop analysis" and "Mesh analysis" are the same.
There is something called "Supermesh" which cannot be regarded as a "loop" or a "superloop".I hope this will clear ur doubt.
Happy learning..............

some said that loop may be consist of some meshes but mesh canot be consist of some loops
this is an opinion i heard but in my opinion i think it is not
they are the same

I tried to show the difference by drawing I think it is easier.
the loop is a mesh but the mesh may be or may be not a loop.
they two can be defined as " The closed path formed by a number of circuit elements"
but in case of loop you may intersect with other elements.
I hope the drawing explains it better.

mesh consists of loops but loop doesnt consists meshes

sorry funster and sabari I doubt your answers and you may refer to the link
http://www.eas.asu.edu/~holbert/ece2...ipes.html#Mesh
and the part of Loop or Mesh Analysis says that
"Mesh (loop) analysis is generally best in the case of several current sources. In loop analysis, the unknowns are the loop currents. Mesh analysis means that we choose loops that have no loops inside them"
that means "A mesh is a loop, but a loop is not necessarily a mesh"

also at the slide 24 of the power point presentation in the following link
http://download.intel.com/education/...ing/Lect12.ppt
it says that:
* A loop is any closed path through a circuit in which no node is encountered more than once.
* To find a loop, start at a node in the circuit. From this node, travel along a path back to the same node ensuring that you do not encounter any node more than once.
* A mesh is a loop that has no other loops inside of it.

and the same words will be found in any circuit analysis book

I hope I helped you.

they are the same, loop and mesh there is no different between them, but the tearm loop have bigger meaning than mesh
loop = # of mesh
regards

in brief,
mesh is a loop with no other loops inside it.

Every loop is a mesh but every mesh is not a loop.
But you can have dependant loops in every circuit but not dependant mesh in every one( I mean the one that have the condition of solving with loop as you know we can solve every circuit with node method but not everyone with loop method their graph must have specific specification but i have not considered exceptions here)

check electronics by malvino.it will clear your concepts.

Loop and mesh r not same ofcourse..
A mesh is a loop, but a loop is not necessarily a mesh"
Mesh cant he any innermeshes r loops..but a loop can ve meshes inside it..
This also just like circuit and a n/w..these r not same..

Every loop is a mesh but every mesh is not a loop.
But you can have dependant loops in every circuit but not dependant mesh in every one( I mean the one that have the condition of solving with loop as you know we can solve every circuit with node method but not everyone with loop method their graph must have specific specification but i have not considered exceptions here)
