Here are some examples of complicated circuits which cannot be reduced to a series circuit or a parallel circuit. One cannot find equivalent resistances using the rules from resistors in series or in parallel. Instead, Kirchhoffs Current and Voltage Laws are used to solve these circuits.

Figure 1 This is an example of a Wheatstone Bridge circuit, where the component labelled G" is a galvanometer. This type of circuit is used to calculate the resistance of an unknown resistor, RX. The other three resistors are variable.
Figure 2 This circuit can be thought of as a T-circuit". It cannot be reduced to series or parallel combinations of resistors because there is more than one emf source.

Kirchhoffs Laws are not the only method of solving such circuits. Different methods have arisen to solve complicated circuits, such as the Superposition Theorem. Some of these methods are easier to use than others, and their simplicity is dependent on the specific circuit to be solved.

The Wheatstone Bridge is a fundamental circuit originally invented to measure resistance. To see how this works look at the following simulated Wheatstone Bridge Experiment. Use the "back" button to return to this point.
