Temperature is directly proportional to Resistance . So that’s why Heat is directly proportional to Resistance .
Q. What is the relationship between resistance and temperature?
The more these atoms and molecules bounce around, the harder it is for the electrons to get by. Thus, resistance generally increases with temperature. For small temperature changes the resistivity varies linearly with temperature: r = ro (1 + a DT), where a is the temperature coefficient of resistivity.

Q. Does higher resistance produce more heat?
A higher resistance produces more heat. The longer the time the larger the amount of heat produced. The amount of current, I. the higher the current the larger the amount of heat generated.
Q. Does more wattage mean more heat?
Power (watts) is volts times amps.” So, more electrical power means more heat just lake a bigger pile of firewood mean a bigger fire and more heat output. So for twice the wattage, you get roughly twice the heat output.
Q. Does higher voltage lower resistance?
According to Ohm’s law, resistance varies directly with voltage. This means that if resistance increases voltage increases… But obviously that’s not how it really works. If I add in a resistor to a circuit, the voltage decreases.
Q. Is current affected by resistance?
The current is directly proportional to the voltage and inversely proportional to the resistance. This means that increasing the voltage will cause the current to increase, while increasing the resistance will cause the current to decrease.
Q. What happens to the current as the resistance decreases?
Answer. Answer: the current in a given circuit is inversely proportional to the resistance in the circuit, which means that the current will decrease if the resistance is increased.
Q. What will happen to current as resistance approaches zero?
Answer. When the resistance in any circuit is equal to zero then the current passing through that circuit will be infinite. We know from Ohm’s law that V=IR. Here, if you consider resistance as zero then the equation becomes V=I(0).
Q. Can you have 0 resistance?
A short circuit has 0 resistance. We use Ohm’s Law V=IR. If R=0, then V=0.
Q. Why do 0 ohm resistors exist?
A zero-ohm link or zero-ohm resistor is a wire link packaged in the same physical package format as a resistor. This format allows it to be placed on the circuit board using the same automated equipment used to place other resistors, instead of requiring a separate machine to install a jumper or other wire.
