Abstract: In the electronic circuit engineering and teaching process，it is necessary to calculate

the DC resist- ance of the capacitor. However，for calculating the DC resistance of some

special-shaped capacitors，the current density method generally used is more troublesome. In this

paper，according to the definition of resistance，combi- ning with the concise relationship between

the series and parallel resistance，the DC resistances of spherical crown capacitor，cylindrical

crown capacitor and positive polygonal capacitor and so on are calculated clearly and the cor-

responding quantitative expression is given.

Key words: DC resistance of special capacitors, spherical cap capacitors, cylindrical cap capacitors, positive polygonal capacitors
