Electrc 2005 is designed for electrical contractors, engineers, inspectors, estimators, and electrical maintenance personnel. It performs wire sizing, conduit fill, motor, lighting, panel schedule, transformer, voltage drop, box fill, fault current, and power factor correction calculations. Built-in reference table from the NEC. Many NEC parameters are supported, including parallel conductors per phase, ambient temperature derating, terminal temperature derating, quantity of current carrying conductors derating, circuit type, voltage drop percentage, and more. Files can be saved to disk and reloaded for future use.

Resistor Values is an electrical engineering program that will calculate the value of a 4 band resistor. Resistor Values will determine the value of a resistor based on the color bands or the reverse, it can display the color bands of a resistance value entered by the user. The trial version of Resistor Values is limited to resistance values of 1000 Ohms (1 KOhm) or less. The registered version shows resistor values up to 99000000 Ohms or 99 MOhms.
