This presentation introduces Kirchhoff's laws of circuit analysis. It begins with an outline that discusses Kirchhoff's current law (KCL) and voltage law (KVL), as well as the purpose, theory, examples, and summary. The theory section explains that KCL deals with the conservation of current at circuit junctions while KVL concerns the conservation of energy in closed circuit loops. Examples are then given to demonstrate how KCL can be used to find unknown currents and KVL can be used to determine potential drops or unknown resistances. In summary, Kirchhoff's laws allow analysis of current, voltage, and resistance in electrical circuits.

5. THEORY
• In 1845 a German physicist, Gustav Kirchhoff developed a pair of laws which
deal with conversation of current and energy within electrical circuits. The rules
are commonly known as: Kirchhoff's Current law.
One law dealing with the current flow around a closed circuit, known as
Kirchhoff's current law and other one algebraic sum of all voltage in any closed
path in a circuit known as Kirchhoff's Voltage law

13. SUMMARY
•
From the above discussion we have realized that if voltage is
greater current will be also greater
Value of Kirchhoff's law equation more accurate than the value
indicate in ammeters
KCL can be used to find the unknown current at any junction point.
Using KVL one can determine the potential drop across a
resistance.
One can determine the current through any resistance or branch
by using Kirchhoff’s laws.
Another important use of KVL is to find the unknown resistance in
a loop.
