For an electronics novice it is sometimes a burden to find the value for a resistor in a circuit or in a storage drawer. Use RCalc to quickly determine the value. Look at the colour bands and then duplicate them on RCalc to determine the value. RCalc rests in your systray (right bottom corner), so its out of sight until you need it. This tool is ideal for scholars and students. By following the ryhm at the bottom of the window you will quickly learn resistor values just by looking at them.
