Resistance against temperature graph

Click For Summary
SUMMARY

The discussion centers on the relationship between temperature and resistance in a filament lamp. As the temperature of the filament increases, its resistance also increases, which can be described by the equation for resistivity. Participants suggest researching the concept of resistivity to understand this relationship better, emphasizing its importance in electrical engineering and physics.

PREREQUISITES
  • Understanding of electrical resistance and Ohm's Law
  • Familiarity with the concept of resistivity
  • Basic knowledge of temperature effects on materials
  • Awareness of filament lamp operation principles
NEXT STEPS
  • Research the equation for resistivity and its application in electrical circuits
  • Explore the temperature-resistance relationship in different materials
  • Study the behavior of filament lamps under varying temperatures
  • Learn about the impact of temperature on semiconductor resistance
USEFUL FOR

Students in physics or electrical engineering, educators teaching thermodynamics, and anyone interested in the principles of electrical resistance and its applications in lighting technology.

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?
