-Select the colors to determine resistance value.
-Able to select between 4, 5, and 6 band color code.
-Selecting the tolerance band gives you min/max resistance offset
-For Light Emitting Diode calculations: Edit the voltage box (V) and the forward voltage box (Vf) to view the current drawn through the resistor and power dissipated by the resistor. Only one LED is supported.
- Go to the LED page and view multiple combinations of LED and Resistor circuits.
-Great for college students/hobbyists who would like to check their work.
