Web26 de abr. de 2024 · A long copper wire has higher resistance than an otherwise-identical short copper wire. Resistance is a measure of how much resistance there is for free … WebA higher resistance coil requires higher voltage to get the same amperage draw as a lower resistance coil. The more amperage you can put through your coil, the more heat you generate ( measured in watts). The lower the resistance the faster you get heating. A 3 ohm coil at 3.7 volt puts out around 4.5 watts. pope francis quotes on mercy and justice

What is the relationship between electrical resistance and …

WebIt is said that alloys are used as heating elements in heaters because they generate more heat due to higher resistance than pure metals. But, higher resistance means lower current flows through the alloys. According to the formula H=I 2 Rt, heat is directly proportional to the square of current and to the resistance. In this way, heat depends ... Web9 de fev. de 2024 · For example, decreasing the resistance (which, in and of itself, would tend to decrease resistive heating) causes the current to increase, which increases resistive heating by a greater factor. Thus, at constant voltage, the net effect of decreasing resistance is to increase power consumption. pope francis quotes on helping the poorWeb5 de abr. de 2024 · I know that there would be less current with higher resistance but since there is more resistance the lack of current would be made up for with more heat generated, so why would there not be more heat generated that would light the resistor on fire or melt it when you add the resistor? electric-circuits electrical-resistance short … sharepoint user not in directory internal

"Web12 de ago. de 2024 · In mathematical terms, the resistance of the first circuit is (R = V/I = 10/1 =) 10Ω, and the second is (25/1 =) 25Ω, so the second – the one that requires greater potential difference to drive the same current, has more resistance. Do you think those two circuits would have resistance? Erm, (pause, three seconds) Probably yeah. " - Higher resistance more heat
