Mosfet switching problem with low value resistor such as 1 ohm

[SArslan]

Hello forum
I am trying to switch mosfet. I am using 1 ohm resistor. My aim is heating or cooling resistor.
First, ı tried basic common source configuration. I used 1 ohm resistor as a drain resistor. My gate voltage is either 3.3 v or 0 v. With this configuration, mosfet cant enter triode region. So how can ı switch mosfet with 1 ohm resistor.

what type of fet are you using?
is it a logic switching fet.
you need more supply voltage to the 1R
i should think. or the fet is faulty
or connected incorrectly.
if 5V supply the IL= 5A so you need >5A fet
