I know there are electrical wizards out there so hopefully you can help me here....I am trying to connect a radio shack 276-036c 5mm red blinking led to a 9v battery... Maximum ratings on the package are 2.5-5vdc supply voltage, 55-80ma ON-state foward current, 0.4vdc reverse current.  Does anyone know with using a 9v battery what resistor i need to use?????  Thanks for your help
