Hi, i have a problem about the relationship of temprature and resistance.

What will be the graph of resistance of a filament (in a lamp) against temprature. In particular, what happens to the resistance of the filament (in a lamp) if i increase its temprature ?

There is an equation that relates resistance and temperature -- try looking up "resistivity" on wikipedia, or you can google resistance versus temperature.

Can you show us the equation?
 

1. What is the purpose of a resistance against temperature graph?

A resistance against temperature graph is used to show the relationship between the temperature and the resistance of a material. It helps determine how the resistance of a material changes as the temperature increases or decreases.

2. How is the resistance against temperature graph created?

The resistance against temperature graph is created by measuring the resistance of a material at different temperatures and plotting these values on a graph. The resulting curve shows the relationship between the two variables.

3. What factors can affect the resistance against temperature graph?

The resistance against temperature graph can be affected by several factors, such as the type of material, the length and thickness of the material, and the temperature range being measured. Additionally, external factors such as pressure and humidity can also impact the graph.

4. What information can be gathered from a resistance against temperature graph?

A resistance against temperature graph can provide insights into how a material behaves at different temperatures. It can also help identify the temperature range at which the material has the highest or lowest resistance, as well as any changes in resistance due to external factors.

5. How is a resistance against temperature graph used in practical applications?

The resistance against temperature graph is used in various practical applications, such as in the design and testing of electronic circuits and devices. It can also be used to monitor the temperature of a system or to determine the thermal properties of a material.
