R is on datasheet right?
The datasheet doesn't give you a way to determine ON resistance unless you're operating at the conditions they specified.

This is for IRF530:

If you're operating at Vgs=10V and Id=8.4A, the Rmax is 0.15 ohms. It could be less, but they don't say how much less. If you operate at different conditions, resistance will be different.
