To start I am very much a beginner at electronics and am very limited in my tools.
I bought a IRF3205 mosfet a few days ago hoping that I could use it in a circuit I have where a 12V power supply at 1.5A is capable of going from the source to the drain to turn on an LED light strip. The would be mosfet controlled by 4.5V supplied by three triple a batteries at it's base.
I was disappointed though to test it and see that this mosfet only outputted less than 9v at the drain(I don't have a way of finding its current). Is there a way to make this mosfet work or do I need to buy a new one? If I need a new mosfet can I get a recommendation?
Again my goal is to control an LED strip—running at 12V, 1.5A—with a 4.5v battery supply going on and off with as few parts as possible, preferably just a single mosfet and no resistors or capacitors
