12v Mosfet Amplifier Circuit. Can i use it. The gate voltage determines the conductivity of the device.
Here the op amp in the circuit is configured as a non inverting amplifier and the input voltage from the 7805 voltage regulator is 4 99v. The speaker using a 2x2 5inch speaker with maximum power 60w see below the video. Of course this mosfet s threshold voltage is at least 3v likely more.
Depending on this gate voltage we can change the conductivity and thus we can use it as a switch or as an amplifier like we use transistor as a switch or as an amplifier.

Full video making of this 12volt power amplifier circuit by using pc power supply former the input voltage about 14v dc asymmetric with current output 5a 20a. A rpi i o pin is high at 3v3. Mosfet stands for metal oxide field effect transistor which has a gate.
