Electric Resistance of Conductors & Semiconductors with Temp Change

Click For Summary

Homework Help Overview

The discussion centers on the relationship between electrical resistance and temperature changes in conductors and semiconductors, exploring the underlying reasons for these behaviors.

Discussion Character

  • Conceptual clarification, Assumption checking

Approaches and Questions Raised

  • Participants discuss how resistance in conductors typically increases with temperature, while in some semiconductors, it may decrease. There is an exploration of the reasons behind these phenomena, particularly focusing on electron behavior.

Discussion Status

Some participants have provided insights into the temperature dependence of resistance, and there appears to be a shared understanding among some members regarding the concepts discussed. However, the discussion does not reach a consensus on all points, and further exploration of the topic is evident.

Contextual Notes

One participant suggests that the original poster could have researched the topic further, indicating a potential expectation for independent exploration of the subject matter.

1.What happens to the electrical resistance of conductors, semiconductors, with increase in temperature? And explain why?
 
Physics news on Phys.org
For conductors, the resistance will increase with T, while for some semiconductors, the resistance may decrease with T, which results from the agitation of the electrons in the valence band
