 Bigger Bigger  Smaller Smaller  Reset Reset

Hey. I am new to electronics and I have a problem that I hope someone won can help me with.
I am trying to build an H-bridge but for some reason the first power mosfets (IRFZ44N) has a very big voltage drop. I only have 5 volts and it uses 3 volts.

On the picture it would be number 1 and 2 that are the problem.

Edit:
i have 6 volts

Well, looking at a datasheet
http://www.irf.com/product-info/datasheets/data/irfz44npbf.pdf
we can see that this is an N-channel MOSFET.
For an H-bridge, one typically uses P-channel  MOSFETs in the 1 & 2 position, for example

"I am new to electronics" + "I am trying to build an H-bridge" = go to ebay and buy one of appropriate size. If you are considering rolling your own, read the below first.
