Mesh Analysis MCQs

Practice Mesh Analysis MCQs with four options, answers and explanations for focused Electronics & Telecommunication Engineering revision.

Question 1
Network TheoryMesh Analysis

In mesh analysis, the principal unknown quantities are usually?

  • ANode voltages
  • BMesh currents
  • CCapacitances only
  • DSource powers only
Report an error
Correct Answer: B. Mesh currents
Explanation: Mesh analysis assigns a current to each independent mesh and uses KVL equations to solve for those currents.

Question 2
Network TheoryMesh Analysis

Two adjacent meshes have currents I1 and I2 flowing through a common resistor R in opposite directions. The voltage drop associated with mesh I1 across the common resistor is?

  • AR(I1+I2)
  • BR(I1-I2)
  • CR/I1
  • DR(I2-I1) only regardless of reference
Report an error
Correct Answer: B. R(I1-I2)
Explanation: With the mesh currents opposing each other in the shared branch, the branch current referenced in I1's direction is I1-I2, so the drop is R(I1-I2).

Question 3
Network TheoryMesh Analysis

A supermesh is used in mesh analysis when an ideal current source lies in a branch common to?

  • ATwo adjacent meshes
  • BA mesh and the reference node only
  • CTwo voltage sources in parallel
  • DTwo resistors in series only
Report an error
Correct Answer: A. Two adjacent meshes
Explanation: A current source shared by adjacent meshes prevents writing an ordinary KVL equation through that branch, so the surrounding meshes are combined into a supermesh.
