kosketinresistanssia
Kosketinresistanssia, often translated as contact resistance, refers to the electrical resistance that occurs at the interface between two conducting materials when they are brought into contact. This resistance arises due to several factors, including the microscopic imperfections of the surfaces, the presence of oxides or contaminants, and the pressure applied to the contact. Even seemingly smooth surfaces have microscopic irregularities, meaning that the actual area of electrical contact is significantly smaller than the apparent surface area.
The magnitude of kosketinresistanssia can vary widely depending on the materials, their surface condition, and the
Minimizing kosketinresistanssia is crucial in many applications. This is often achieved through careful selection of materials,
