I had 2 people telling me 2 different things...so I don't know the real answer. Does resistance go up or down with an increase in temperature?
Femme_physics said:Can it stay constant, too?
No, resistance does not always increase with temperature. This relationship depends on the material and the type of resistance. In some cases, resistance may decrease with an increase in temperature.
Resistance typically increases with temperature because the movement of atoms and electrons within the material increases, causing more collisions and hindering the flow of electricity.
Yes, there is a formula called the temperature coefficient of resistance (TCR) that can be used to calculate the change in resistance with temperature for a specific material. TCR is measured in units of ohms per degree Celsius (Ω/°C) or ohms per degree Fahrenheit (Ω/°F).
Most metals have a positive temperature coefficient of resistance, meaning that their resistance increases as temperature increases. Some examples include copper, silver, and gold.
Yes, temperature can significantly affect the resistance of electronic components. High temperatures can cause changes in the material's properties, leading to variations in resistance and potential damage to the component. It is essential to consider temperature when designing and using electronic circuits.
