normaalijohtimeen
Normaalijohtimeen refers to the state of a material where it exhibits electrical resistance. In this condition, the material allows electric current to flow, but some energy is dissipated as heat due to the interaction between the moving charge carriers and the atoms of the conductor. This phenomenon is described by Ohm's Law, which states that the voltage across a conductor is directly proportional to the current flowing through it and the resistance of the conductor. The unit of electrical resistance is the ohm, symbolized by the Greek letter omega (Ω). Factors influencing the resistance of a normal conductor include its material composition, length, cross-sectional area, and temperature. Most common conductive materials, such as copper and aluminum, behave as normal conductors at room temperature.
This state contrasts with the phenomenon of superconductivity, where certain materials, when cooled below a critical
