The Circuit Laws:

To all who know how to solve the problems mathematically, here’s something to work out. Please apply yourself.

Kirchoff's Current Law:

At every junction the algebraic sum of all currents is zero. This is embedded in the classical Continuity Equation arising out of the Conservation of Charge.

Kirchoff's Voltage Law:

The algebraic sum of all voltages around a closed loop in the circuit is zero. Its source can be seen in the Law of Conservation of Energy.

Exercise:

Please apply Kirchoff's Current and Voltage Laws to the figure shown above. I wonder how the Electricity Board managed to solve the networking problem.

Reflection:

—But did it really? Could it be that it’s a well-designed well-built nest of corruption? The connection to the house snaps you don’t know when, and you call the electricity serviceman; on restoring it you are obliged to pay him a pretty generous tip.
