In the following schematic, a 9.0V battery is used to power a blue LED (Light Emitting Diode). The LED needs 3.1V across its terminals in order to light up. The resistor is used to limit the current through LED to be around 1.3 mA. Determine the resistance of the current limiting resistor ( note the color band shown may not be correct).
