how does look resistance when coming from atom to atom? I mean what is making that resistance, something with space between them or atomic forces?
Resistance is a physical property that describes the opposition of a material to the flow of electric current. It is measured in ohms (Ω) and is dependent on various factors such as the material's composition, temperature, and length.
Resistance is determined by the microscopic interactions between atoms in a material. When an electric current flows, electrons move from atom to atom, and these atoms "resist" the flow by hindering the movement of electrons. This results in a drop in voltage and the generation of heat.
The main factors that affect resistance are the type of material, its length, and its cross-sectional area. Additionally, temperature and impurities in the material can also impact resistance.
The resistance of a material is determined by its atomic structure and the ease with which electrons can move through it. Materials with tightly bound electrons, such as metals, have lower resistance compared to materials with loosely bound electrons, such as insulators.
As temperature increases, so does the resistance of a material. This is because higher temperatures cause atoms to vibrate more vigorously, making it harder for electrons to move through the material. This effect is more pronounced in metals, which have a higher thermal coefficient of resistance.
