... a working circuit in different combinations with a resistor. They will show how the time constant can be calculated experimentally as well as theoretically. One of the most underlying laws when dealing with electronics, which was introduced by Georg Ohm in 1821 [Gough], is Ohm's Law. These experiments will validate this law. It will also investigate how the characteristics of a circuit may change when introducing resistors in parallel or series and as a result, verify the voltage divider rule. They will look at voltage drops around complete loops and how by manipulating a circuit can be used to make complex networks simpler, thereby validating Kirchoff's Voltage and Current Laws, and Thevenin's Theorem. "The Wheatstone bridge circuit was developed in 1843 by Charles Wheatstone in order to determine the values of unknown resistances" - [Gough], This will be investigated to check the validity of the Wheatstone bridge theory and prove it's usefulness. Theory Experiment ...
