Consider the transistor with threshold voltage,$$ VTN$=0\mathrm{.}75$VVTN$=0\mathrm{.}75$V $$in the given figure:

$$

At the NMOSFET, W over L $=10$ over $1$ is shown. The resistor $(100$k$)$ is connected between D C node and drain. The gate terminal is connected to drain terminal.

The drain current for the transistor in the given figure if $=0,$ K$\text{'}$n $=100$ A$,$ and the W $/$ L ratio is changed to $20/1$ is $\_\_\_\_\_$Blank A$.$
