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.

RVal is a program for Electronic ... will find the nearest preferred resistor values satisfying certain criteria or all ... into a spreadsheet or similar program.
