One of Kirchhoff’s
laws is his view on how electrical current
travels in a circle, or rather, a closed
loop. According to the textbook, “Physics
with Modern Physics” by Randall D. Knight,
“…the total voltage while moving in a
circle or closed loop is zero.” In other
words, the sum of incoming currents = 0.
This law is predicted on the fact, a
charge can neither be created nor
destroyed---in essence, it is the conservation
of energy law. The importance of
this law lies in the fact that voltage
must be accounted for; that is, voltage
coming out of a junction must equal zero.
If not, varying degrees of property can be
affected:circuits can be tripped or,
worse, the housing carrying the current
can ignite consequently causing a fire.
The importance of this law lies in
calculating voltage, resistance, and current
in electrical analysis.
