Possible to Cook with a Wok on an Electric Hot Plate?
Impossible is a strong word, but yes its near enough impossible as there is insufficient surface area touching to transfer the heat through, and hot plates do not have good heat .. not sure of the word, but they don't transfer heat well to things which are not touching them.  

You can get flat bottomed woks which are more suited to this set up, but even then if you are moving the wok about a lot you still end up with the contact being lost quite a bit, and so not as much heat being transferred as you might want.  

I've always found woks to work best on gas.  In fact gas is just best, full stop.
