WebJoule heating can also be described at a more microscopic level: In the flow of electricity electrons move through the electrical path whose conductivity is limited. As flowing electrons smack into atoms that comprise the molecules of the conductor (for example the atoms of the molecules of a nichrome heater wire), the electron's energy is ... WebTo do this, we have a wire with a diameter of 0.12 mm. The simplest calculation of nichrome length in power without taking into account heating is performed as follows: We determine the current strength: P = UI. I = P / U = 10/12 = 0.83 A. Calculation of the resistance of a nichrome wire is carried out by Ohm's law: R = U / I = 12 / 0.83 = 14.5 Ohm the boy and the bayonet https://dreamsvacationtours.net
