- Consider the circuit
- shown. Resistors and
- are neither in series nor in
- parallel due to the placement
- of . The same applies to
- and .
- Such circuits can be
- solved by the branch method.
- The first step invokes
- Kirchoff's first rule, namely
- that the sum of all currents
- flowing into any point in the
- circuit equals the sum of all
- currents flowing out. The
- current flowing into point A is
- arbitrarily labeled , and the
- current flowing from A to C is
- arbitrarily labeled and
- assigned an arbitrary
- direction.
