450watt जनरल घरेलु , loundry iron 1000-1500watt electric power use(ख़र्च)
B. automatic ele. iron
⭐ - Thermostat - connected in series with heating aliment and working like be (gain heat) switching act with Heat diffusion coefficient Movable contact bimetallic leaf fixed on sole plate
Sole plate cold bimetallic plate straight flow current continu , blub (+ H resis in series)parrelal with heat ale.
Adjustment temp by thermosate
High temp 🔥 lilone , सूती
Low temp 🔥 terilone,silk
different metals = different diffusion temperature
heat diffusion coefficient - fe◀पीतल (brass)
* dont touch plate setting because only owner known bimetallic plate diffusion coefficient
