Hi guys,
I'm back again after your help worked out so well last time giving me an understanding. Now I am required to build a power mosfet switch with changing positions and was hoping for some help / advice on my ideas / results.
The first task is;
Draw a low side pwoer switch using a power mosfet as the switch for driving a 10 amp load.
To which I have drawn this

the second task is;
if the switch becomes inductive (20uH) and it takes 200ns to turn off to 0A what will the fly back voltage be present at the transistor? draw a circuit marking flyback voltage and polarity?
This one I am unsure of because in my text I can't find any equations that I can utilize because I have not been given the applied voltage in the first place I only have the inductance rating, time and ona nd off amp ratings? Can anyone shine some equations / light on this query?
regards
Samuel
