I have two 1.5 Volt batteries, a Red 3V LED, and some cables.
The batteries I have connected in series like
From my studying I believe I should now have 3 Volts ready when I need.
I connected two copper cables, 1 at the negative end and 1 at the positive end.
I believe the volts should push the current from the negative end of the battery towards the LED and then back out towards the positive end of the battery.
I noticed the length of the leg cable on one pin on the LED is longer than the other, I have tried two different LEDS both ways and the LED still does not light.
I have attached a picture below.
I have also tried inserting a 270 ohm resistor at the end of the negative cable of the battery but before the LED - This still doesnt allow the LED to light.
What am I doing wrong here? Is my understanding correct?
I have also tried lighting the LED with just one battery, it does not work either.
