Generally, the mesh current method results in fewer equations than the node voltage method.

A circular queue has been implemented using a singly linked list where each node consists of a value and a single pointer pointing to the next node. We maintain exactly two external pointers FRONT and REAR pointing to the front node and the near node of the queue, respectively. Which of the following statements is/are CORRECT for such a circular queue, so that insertion and deletion operations can be performed in O(1) time? I. Next pointer of front node points to the rear node. II. Next pointer of rear node points to the front node.

A

I only

B

II only

C

Both I and II

D

Neither I and II

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.

A

Both (A) and (R) are true and (R) is the correct explanation of (A).

B

Both (A) and (R) are true, but (R) is not the correct explanation of (A).

C

(A) is true, but (R) is false.

D

(A) is false, but (R) is true.
