Ok, I want to test out my N-Channel MOSFET (an IRF620). I plugged it into my breadboard and wanted to try a simple test: connect a battery to an LED, and control whether the LED is on by attaching/detaching a second battery from the gate.
All of my resistors are 100k-Ohms. The setup is: the middle-pin of the MOSFET goes to a resistor, to the LED, to the positive end of the battery. The negative end of the battery goes to another resistor, and finally to the right-most pin of the MOSFET. I assume that those are source and drain, correct?
Well, even if nothing is plugged into the gate, the LED lights. What am I doing wrong, and how do I set up the circuit properly?
Thanks!!
