If they are, then the current flowing through them would be small. And 
electrical energy converted into heat E =I^2Rt would be small too. And the 
heating element wouldn't be much useful.
So are heating elements made of low resistance materials, then? Why are 
heating elements usually made of nichrome?
Thanks.
