That will depend on the temperature coefficient of resistance of the device, which could be positive (i.e. resistance increases with increasing temperature), negative (i.e. resistance decreases with increasing temperature), or zero (i.e. resistance is unaffected by temperature changes).

Why Cable gets heated when current flows more than its rated current why?
Because if the rated current is lower than the actual current, it causes resistance to the electrical flow which in turn is dispelled as heat.
What happens to the Eiffel tower when it is heated?
When the Eiffel tower is heated, it expands and becomes wide and taller, but not so much. This will increase the size of the Eiffel tower. It will decrease when it is in Winter.
Glow wire testing?
Glow wire testing is a safety evaluation method used to assess the flammability and heat resistance of materials, particularly in electrical equipment. During the test, a heated wire is applied to the material for a specified duration to determine whether it ignites or continues to smolder after removal. This testing is crucial for ensuring compliance with safety standards, particularly in consumer electronics and appliances, to prevent fire hazards. It helps manufacturers identify materials that can withstand high temperatures and reduce risks associated with electrical failures.
What does sandstone change to?
That depends on what happens to it. If it is sufficiently heated and compressed it will metamorphose to quartzite.
How were Cahuilla Indian houses heated?
The sweat house were heated with fire.
What happens to electrical resistance of most conductors when heated?
Resistance goes up creating more heat which eventually leads to an open circuit.
What happens to the resistance of a common ohmic resistor when it is heated?
When a common ohmic resistor is heated, its resistance typically increases.
What happens to the resistance of a metal when it is heated?
its resistence considerably decreases
What happens to the electrical conductivity of a metal when it is heated?
it wil expand
What happens if a thermistor is heated?
the thermistors respond negatively to the temperature and their resistance decreases with the increase in temperature. Since the resistance of thermistors is dependent on the temperature, they can be connected in the electrical circuit to measure the temperature of the body.

What happens to copper wire when heated?
When copper wire is heated, it expands due to thermal expansion. As it gets hotter, the electrons in the copper atoms move more freely, increasing electrical resistance. Excessive heating can cause the copper wire to melt and ultimately vaporize.
What happens to the resistance of a copper wire when it is heated?
The resistance of a copper wire increases when it is heated. This is because heating the wire causes the metal ions to vibrate more, increasing collisions with the electrons and hindering the flow of current, therefore increasing resistance.
Why filament gets heated?
Filament gets heated when an electric current passes through it, causing resistance in the filament wire. The resistance converts electrical energy into heat energy, which then causes the filament to reach high temperatures and emit light.
What car device changes electrical energy into heat?
Electrically heated seats, wing mirror defrosters and rear window defroster.
Why the water gets heated when current is passed through carbon rods in it?
The carbon rods have electrical resistance. Thisi causes them to heat when current is passed through them. The water gets heated by the carbon rods.
What does electrocoagulation entail?
A heated needle connected to an electrical device is used to cauterize or burn the tubes. Electrocoagulation is the most common method of tubal ligation.
How the filament is heated?
The filament in a light bulb is heated by passing an electric current through it, which causes the filament to resist the flow of electricity and heat up due to its electrical resistance. The heat generated by the filament causes it to emit light, producing illumination.
