Appliances based on heating effect of electric current are:
1) Electric heater
2) Electric iron
3) Microwave oven
4) Induction cooker
Finely heated platinum wire is used in surgery rather than knife because melting point of platinum is is very high so it does not get melted easily  when heated for cutting the tissues while doing surgery.
