Unable to correctly simulate MOSFET
818 1

So, I'm trying to simulate a simple MOSFET behavior as a switch but I'm haveing odd values. I show below an image with an example. The Vgs for this MOSFET is 20V and so the current should be zero and the voltage 10V when the source is at 10V.  ![Screen Shot 2020-04-14 at 22.50.44.png](//image.easyeda.com/pullimage/FokLG842T2gbHYJw3Pj6fL0vEViBN4UwHmJ0YaVi.png)

Please read the datasheet for the device you have selected carefully. The 20V value of Vgs is the Absolute Max Vgs that can be applied without damaging the device. At a Vgs of 10V as your sim has set up, the device is turned hard on and is drawing the figure of 532.5A. Multiply that by the Rds_ON value of the device and that's where roughly 9V Vds comes from. The Ammeter has some internal resistance (the inductor probably has a default value of zero resistance).
