Question

I am studying in engineering, i want to finish my assignment. So I want switching losses of MOSFET..?

Answer 1

The losses will be: the switched current through the MOSFET, squared, multiplied by the Rds_on; the resistance of the drain-to-source channel when the device is 'on'.  

For power MOSFETs Rds_on can range from a few milliOhms to a few Ohms, depending on the part number (and how it is constructed internally).

Here is a chart of many MOSFETs that lists their Rds_on values (along with other parameters):

Look at the RDS(on) columns
