Suppose we want to find the current i1?

What are the equations needed to solve for the 7 unknowns?

What is Kirchhoff's Current Law (KCL)?

What is Kirchhoff Voltage Law (KVL)?

How do we apply KCL to each node?

A closed path or a loop is defined as starting at an arbitrary node, we trace closed path in a circuit through selected basic circuit elements including open circuit and return to the original node without passing through any intermediate node more than once.

The algebraic sum of all the voltages around any closed path in a circuit equals zero.

Assigning a positive sign to a voltage rise ( -to + ) and assigning a negative sign to a voltage drop ( +to -).

We apply KVL as follows: Loop 1 0 + - = 1 2 5vv Loop 2 0 + - = 4 32v v v.

Example for the circuit shown apply KCL to each node a, b, c, and d.
