Hello, I am using IRF830 MOSFET as a switch, I have 4 cooling fans . Each fan works at 5v DC and .3 A. I connect them in parallel and used the mosfet to switch them on and off. I am not too familiar with MOSFETs, and I am facing a situation that I colud not understand, the problem is:
I connect the MOSFET as follw:
The gate is connected to arduino to switch fans on and off,
the source is connected to ground of the 5 v power supply,
The drain is connected to the negative of the fans
The positive of the fans is connected to thepositive of the power supply.
When fans are switched on with the MOSFET connected, they don’t run as fast as if they are connected without it “ they run faster when connected to the supply directly” ,, so what is the reason for that..? And how can I make them run at the same speed??
