You can keep a resistor at a constant temperature by using a heat sink to dissipate excess heat generated by the resistor. This helps maintain a stable operating temperature and prevent overheating. Additionally, ensuring proper ventilation and using a resistor with a high power rating can also help regulate its temperature.
Electrical appliances such as refrigerators and air conditioners use a thermostat to monitor the temperature and adjust the operation of the appliance to maintain a constant temperature. When the temperature rises or falls outside the set range, the thermostat signals the appliance to turn on or off to keep the temperature stable.
You can keep water heated to a constant temperature by using a water heater with a thermostat that monitors and regulates the temperature. Insulating the water tank can also help maintain heat. Additionally, using a recirculating pump or a tankless water heater can help ensure a constant supply of hot water.
Keeping temperature constant is important because many processes and reactions are temperature-dependent. Fluctuations in temperature can affect the outcome and efficiency of these processes. Additionally, temperature stability can also prevent damage or degradation of sensitive materials or substances.

Body temperature remains relatively constant regardless of external weather conditions. However, extreme cold or hot weather can affect how the body maintains its temperature through mechanisms like shivering or sweating to keep it within a normal range.
A non-ohmic resistor doesn't have a constant resistance. A ohmic resistor has a constant resistance.
How do are body's maintain a constant temperature?
A resistor by itself has no time constant. For a circuit to have a time constant it must contain either capacitors or inductors.
All mammals are classified as endotherms, which means they have some ability to keep a constant body temperature. However, endothermy is not complete, so a disease or extreme outside temperatures could overpower the mammal's ability to keep its body temperature constant.

A resistor will not change its value, unless the voltage exceeds the designed power capacity of the resistor. As the voltage increases, the current will increase, if the current gets too high it will cause the temperature of the resistor to increase, if the temperature exceeds the power rating of the resistor then the resistance WILL change. If it goes too High in temperature the resistor will open and current will no longer flow. A resistor is used to control current, and indirectly the .voltage depending on the application. Hope This helps. You must use Ohms Law to see the relationship.
it can go up or down
Temperature fluctuation is where the temperature does not stay at a constant rate. It will keep getting colder or warmer and not cease to a certain degree.
Electrical appliances such as refrigerators and air conditioners use a thermostat to monitor the temperature and adjust the operation of the appliance to maintain a constant temperature. When the temperature rises or falls outside the set range, the thermostat signals the appliance to turn on or off to keep the temperature stable.
V=IR by ohms law. Voltage across the resistor is the product of current flowing and resistance of the conductor at constant temperature.
A ballast resistor is an electrical resistor whose resistance varies with the current passing through it, thus maintaining a constant current.
