I want to use a MOSFET that can handle high current use for switching, so I decided to use the external MOSFET for 3d printer. I tested it out on other loads such as motor, LED, relay it is able to conduct when I connect the control to a 12v voltage. But when it comes to a car bulb it doesn't seem to light up.
The car bulb is able to light up when connected directly to the 12V car battery, but cant light up when connected through the MOSFET.
The MOSFET power source is from a 12v battery, the load part is connected to the light bulb and the control pin is connected to a 12v dc source, and has also tried to connect it directly to the 12v battery. In which both cases are able to switch on other loads but not the car bulb.
The VGS of the MOSFET is 10V, in which when 10V is applied across the gate the source and drain of the MOSFET is suppose to conduct current.
