In this case, the resistance will increase in inverse proportion to the wires new diameter, and in direct proportion to the wires new length.
To find the percent increase from 55 mph to 70 mph, you first calculate the difference between the two speeds: 70 mph - 55 mph = 15 mph. Then, divide this difference by the original speed (55 mph) and multiply by 100 to get the percent increase: (15/55) * 100 ≈ 27.27%.
The efficiency of an electric furnace can vary but typically ranges from 95-100%. This means that most of the electricity used is converted into heat, with very little wasted energy. Regular maintenance and proper installation can help optimize the efficiency of an electric furnace.
I think it will increase from the present 15-20 percent of electricity, perhaps up to 30 percent in the US and Europe, in the next 20 years
You lose energy to mechanical loss, heat escaping and electrical resistance.
No, electric heaters are not 100 percent efficient. While they convert all the electricity they consume into heat, some heat can still be lost through the material of the heater itself, especially if it is not well insulated. Also, some heat may escape into the surrounding environment instead of heating the intended space.
