This is an easy-to-use utility that helps you calculate the value of any resistor, according to the text or to the color code printed on its surface. In order to find out the value of a resistor (plus the tolerance and the temperature coefficient), you have to select the number of bands and to click on their color. The second page of the program helps you identify the RGB colors in a certain resistor picture. In case of the SMD-type resistors, the procedure is similar: first, select their model; second, enter the printed letters and the numbers - by using either your mouse or your keyboard. Finally, the fourth program page allows you to calculate the total resistance of a circuit containing two resistors connected in series or in parallel.
