I am trying to add an LED to a NiMh charger for 5 AA battery pack
(total voltage about 6.93) to be able to see that is actually turned
on.

I have seen some chargers that have the dropping resistor and LED in
series  with each other and then this combination is in parallel with
another resistor of lower ohms which goes to the battery pack: examples

(82 ohm and LED) in parallel with (a resistor of 24 ohms) - used for
charging 4 AA batteries


(47 ohm and LED) in parallel with (a resistor of 18 ohms) - used for
charging 2 AA batteries


I can calculate the resistor for the LED but any thoughts on what the
other resistor should be? or what things to take into account in
choosing this resistor ?

Thanks
Ali
