1st week W 1.8.14 Changing brightness with resistor

I placed a 100k, 1k, and 10k resistor in a separate row connecting to the negative power.  Each had a LED light.  I placed a jumper wire from the positive power to LED row.  With power cord, all light lit up.  The 100k was the brightest (red) and 10k (yellow) was the dimmest which had the most resistance to the energy produced
