-as many as 6 one volt batteries

-a 25 ohm resistor

-a 100 ohm resistor

-a 3300 ohm resistor

-a LED

The LED needs at least two volts and 10 mA to light up, and anything over 25mW of power will burn it out.

The closest I got was just using two volts of power and 125 ohms of resistance, which game me 16mA of current but my power was 32 mW and everything else I tried either gave me too much power with the small resistors or not enough current with the 3300 ohm resistor.

Any hints/tips/ideas are appreciated.
