Give examples of numerical problems in network analysis with solutions and justification where,
(1) Superposition theorem may be more useful than mesh/nodal analysis.
(2) The use of Thevenin's/Norton's equivalent circuit may be more useful than mesh/nodal analysis.
(3) Mesh analysis may be more useful than nodal analysis.
(4) Nodal analysis may be more useful than mesh analysis.
(5) Source transformation, voltage/current division rules are applied.
