Dabi da karkashin hanyar da kuma karkashin tsakiyar hanyar
Daɗiƙar gudummawa na ƙarin daɗiƙa da kuma tattalin daɗiƙa na abubuwa a cikin yankunan da dama, tun daga IEC standards.
"Bayanin ƙarin daɗiƙa da kuma tattalin daɗiƙa na abubuwa a kan faren lasshi. Ƙarin daɗiƙa ya shafi da mafi girgirin abubuwa a cikin abubuwa. Ƙarin daɗiƙa na copper kamar IEC 60028, ƙarin daɗiƙa na aluminium kamar IEC 60889."

Ƙarin Daɗiƙa
Ƙarin daɗiƙa ce babban alamomin abubuwa wanda yake tsara da yadda aka iya daɗiƙar karamin lafiya.
Tattalin Daɗiƙa
Tattalin daɗiƙa ce muhimmanci ƙarin daɗiƙa. Yana nuna kyakkyawan abubuwan da suka daɗiƙar karamin lafiya.
Farkon Lasshi
Farkon lasshi na ƙarin daɗiƙa na abubuwan da suka daɗiƙar karamin lafiya.
Rumun Farkon Lasshi
ρ(T) = ρ₀ [1 + α (T - T₀)]
Amsa:
ρ(T): ƙarin daɗiƙa a lasshin T
ρ₀: ƙarin daɗiƙa a lasshin T₀ (20°C)
α: farkon lasshi na ƙarin daɗiƙa (°C⁻¹)
T: lasshi na yi aiki a °C
