I2Rhäviöitä
I2Rhäviöitä is a Finnish term that translates to "I2R losses" or "I-squared-R losses" in English. It refers to the energy dissipated as heat in a conductor due to the flow of electric current. This phenomenon is a direct consequence of Ohm's Law and the Joule heating effect. When an electric current (I) flows through a material with electrical resistance (R), a certain amount of power is converted into thermal energy. This power loss is mathematically expressed as P = I²R.
The I2Rhäviöitä are an unavoidable aspect of electrical power transmission and the operation of most electrical
