Assertion (A): All the mesh currents are necessarily the loop currents but all the loop currents may not be the mesh current. Reason (R): The mesh current is the current which flows only around the perimeter of a mesh.
Assertion (A): All the mesh currents are necessarily the loop currents but all the loop currents may not be the mesh current. Reason (R): The mesh current is the current which flows only around the perimeter of a mesh. Correct Answer Both (A) and (R) are true and (R) is the correct explanation of (A).
Concept:
- A loop is a closed path in a circuit where two nodes are not traversed twice except the initial point, which is also the final one.
- But in a loop, other paths can be included inside.
- A mesh is a closed path in a circuit with no other closed paths inside it.
- In other words, a loop with no other loops inside it.
This is explained with the help of the following diagrams:

We, therefore, conclude that Both (A) and (R) are true and (R) is the correct explanation of (A).
