Kirchoff's Law
Background
Solution of linear systems can be applied to resistor network circuits. Kirchoff's
voltage law says that the sum of the voltage drops around any closed loop in the
network must equal zero. A closed loop has the obvious definition: starting at
a node, trace a path through the circuit that returns you to the original
starting node.
Network #1
Consider the network consisting of six resistors and two battery, shown in
the figure below.
There are two closed loops. When Kirchoff's voltage law is applied, we obtain
the following linear system of equations.
Network #2
Consider the network consisting of nine resistors and one battery, shown in
the figure below.
There are three loops. When Kirchoff's voltage law is applied, we obtain the
following linear system of equations.
Network #3
Consider the network consisting of six resistors and two batteries, shown in
the figure below.
There are three loops. When Kirchoff's voltage law is applied, we obtain the
following linear system of equations.
