1. KCL is a law stating that the algebraic sum of the currents flowing into any node in a network must be zero.
2. KVL is a law stating that the algebraic sum of the voltages around any closed path in a network must be zero.
A helpful mnemonic for writing KVL equations is to assign the polarity to a given voltage in accordance with the first sign encountered when traversing that voltage around the loop.
3. The following is the basic method (or fundamental method or KVL/KCL method) of solving networks :
1. Define voltages and currents for each element.
2. Write KVL.
3. Write KCL.
4. Write constituent relations.
5. Solve.
