Higher resistance more heat
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. Web9 de fev. de 2024 · Let’s consider our toaster with two alternatives, copper for less resistance and graphite rods for higher resistance. Both of them will oxidize at the temperature required to make a toast. Copper will also be very complicated to feed. It will require a low voltage, but a high current.
Higher resistance more heat
Did you know?
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. Web15 de mar. de 2024 · The heat a resistor produces is the energy loss given by I2 R. If you assume a fixed voltage and resistance, then I= V/R so the heat produced is given by (V/R)2(R)= V2/R. By golly it is true! LOWER resistance will produce a higher current and that is more important than the resistance! Lower resistance will produce more heat.
Web5 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 … WebWhat makes heat resistant proteins heat resistant?

Web16 de ago. de 2024 · But rather than switching from copper cables to iron ones in order to increase resistance of the whole circuit, you use the power switch at your heater to increase the resistance of the heater alone. So you still get (almost) twice the resistance and less power dissipated. You pay smaller power bill, but your room is colder now.
