2. At the end of the presentation, we should be able to:
Explain Kirchhoff’s Current Law (KCL) in simple terms.
State the formula and properties of KCL.
Solve sample circuit problems using KCL.
Use illustrations and diagrams to show how KCL works.
Identify the importance and applications of KCL in real life

3. Kirchhoff's Current Law:
The Foundation of Circuit Analysis
Welcome to this presentation on
Kirchhoff's Current Law (KCL), a
fundamental principle in electrical
engineering. We'll explore its origins,
its meaning, and its profound impact
on how we understand and design
electrical circuits.

4. e is most famous for formulating Kirchhoff’s Laws in
1845:
Kirchhoff’s Current Law (KCL): Current entering a
junction equals current leaving.
Kirchhoff’s Voltage Law (KVL): The sum of voltages
around a closed loop is zero.
Other contributions:
He worked with Robert Bunsen (the one from the
Bunsen burner) and together they discovered the
chemical elements cesium and rubidium using
spectroscopy.
He also laid foundations for understanding blackbody
radiation, which later helped in the development of
quantum physics. Gustav Kirchhoff

5. Kirchhoff’s Current Law Formula∑Iin​=∑Iout​
or∑I=0 where the symbol
∑
means ‘ the sum of

6. Example formula:
I1+I2−I3−I4=0
I1​+I2​=I3​+I4​which rearranges to:

7. summary of the result
I1=30
I2=50A
I3=110
I4=85A
I5=-55
