12. The mesh current method is based on Kirchhoff's current law.
13. The node voltage method is based on Kirchhoff's voltage law.
14. Using the mesh current method, find the branch current, IR1, in the above figure.
15. When assigning branch currents, you need not be concerned with the direction you choose.
16. Generally, the mesh current method results in fewer equations than the node voltage method.
17. Third-order determinants are evaluated by the expansion method or by the cofactor method.
18. Find the node voltage VA.
