Third-order determinants are evaluated by the expansion method or by the cofactor method.
Answer: Option A
Generally, the mesh current method results in fewer equations than the node voltage method.
Answer: Option B
When assigning branch currents, you need not be concerned with the direction you choose.
The branch current method is based on Kirchhoff's voltage law and Kirchhoff's current law.
The mesh current method is based on Kirchhoff's current law.
