I built a simple circuit consisting of 2 battery holders each including x2 1.5v batteries, a slide switch, a LED and a 100 ohm resistor.
The current I measured with a multimeter when the 2 battery holders are connected in series (and the switch ON) is 25.9 mA:

I then connected the battery holders in parallel by connecting the positive contacts of the battery holders with the red jumper cable and the negative contacts of the battery holders with the black jumper cable:

This time the measured current is 6.72 mA. Shouldn't it be greater than when the battery holders are connected in parallel?
