Circuit Aid contains a resistor circuit analysis tool that can build up to an 18 resistor series-parallel circuit. This tool will display voltage, amperage, and power used by every resistor in the circuit by means of mesh analysis. In addition, the program also contains a resistor color band calculator.

Circuit Aid is no longer available for download because it has now been incorporated into a $9.95 shareware app called Physics 101
