Detailed Solution
Download Solution PDFMesh Analysis:
It is based on Kirchhoff's Voltage Law (KVL). It is a method of to obtain a set of simultaneous equations that, when solved, will provide information about the current flowing through each branch.
Mesh current method can’t be applied for the following two conditions.
- This works for circuits that are planar. It can’t applicable for non-planar circuits.
- It can’t applicable when the current source shared by two meshes.
For a network having N nodes and B branches, the number of simultaneous equations to be solved to get the unknowns
= Number of KVL equations
= number of independent loop equations
= B - N + 1
Additional Information
- Planar circuits are the circuits that can be drawn on a plane surface with no wires crossing each other.
- Non-Planar circuits are the circuits that can be drawn on a plane surface with some wires crossing each other.
- Mesh current method and nodal analysis can be applied for planar circuits only but not for non-planar circuits.
- Mesh current method is the application of Kirchhoff’s Voltage Law (KVL) whereas the nodal voltage method is the application of Kirchhoff’s Current Law (KCL).
