WebElectric resistance heating is 100% energy efficient in the sense that all the incoming electric energy is converted to heat. However, most electricity is produced from coal, gas, or oil generators that convert only about 30% of the fuel's energy into electricity. Because of electricity generation and transmission losses, electric heat is often ... WebJun 13, 2024 · An air core coil with with 3Ω dissipates 50W on average. The coil is a donut weights ~817 grams and perfectly layered thus heat transfer wouldn't be obscured with air gaps if it were hand wound. Coppers specific heat is ~0.4 J/g °C would the coils temperature rise be roughly (50 * 0.4) / 817 thus a rise of 0.024°C per second? Greatly appreciated. WebCOIL TEMPERATURE (Degrees C) * Operate voltage corrected for temperature change. Vf = Vo (Rf/Ri) * Actual coil temperature by “change-of-resistance” method. Tf = Ti + Rf/Ri (k+Tri) – (k+Trt) [k = 234.5 for copper wire] Using the above formulas and basic algebra, one can: Calculate the expected resistance change over temperature. barua ya kufunga biashara tra
