Abstract

The electric hotplate is described has a laminated structure in which the heating element comprises strips of positive temp. coefft. of resistance material R on an insulating substrate. The strips are connected in a series parallel arrangement between conductors A,X,Y,Z and B. The interconnecting conductors X,Y and Z are of a material with a negative temp. coefficient of resistivity. Strips are screen printed or the ceramic be insulative covering of a metal plate from a viscous ink of powdered nickel or cobalt plus glass.
