Nodal Analysis is based on

  • A.Kirchhoff's current law
  • B.Kirchhoff's voltage law
  • C.Ohm's law
  • D.Maxwell's law

Answer: A

Nodal analysis is based on Kirchhoff's current law.

In nodal analysis one node is chosen as reference and the voltages of the other nodes are the unknowns. At each node, the currents in the connected branches, written in terms of the node voltages using Ohm's law, are made to sum to zero, which is KCL. The resulting equations are solved for the node voltages.

Mesh (loop) analysis is the method built on Kirchhoff's voltage law. Ohm's law is used within both methods but is not their basis, and Maxwell's name is attached to loop currents, not to nodal analysis.
