Can the Voltage Drop PTC Thermistor Homework Statement be Solved?

Click For Summary
SUMMARY

The discussion centers on the homework problem regarding the Voltage Drop PTC Thermistor, specifically the interpretation of the voltage drop in relation to resistance. Participants clarify that the task requires creating a graph of "voltage drop per grain boundary" versus the PTC, calculated over the range of Rmax-Rmin, rather than the initially assumed voltage drop versus Rmax-Rmin. The existing graph provided in the homework illustrates Resistance versus Temperature for various voltages, which differs from the required analysis.

PREREQUISITES
  • Understanding of PTC thermistors and their characteristics
  • Familiarity with graphing voltage drop and resistance
  • Knowledge of grain boundaries in materials science
  • Basic principles of thermodynamics related to temperature and resistance
NEXT STEPS
  • Research how to graph "voltage drop per grain boundary" in PTC thermistors
  • Study the relationship between resistance and temperature in thermistors
  • Explore the concept of grain boundaries and their impact on electrical properties
  • Learn about the mathematical modeling of voltage drop in thermistors
USEFUL FOR

Students studying electrical engineering, materials science, or anyone working with PTC thermistors and their applications in circuit design.

I am not sure exactly what this question is asking for, especially in regards to the voltage drop. How would the graph of voltage drop vs Rmax-Rmin be any different to what is already provided?

I'm not sure I can solve the whole problem but since you haven't had a better answer...

The existing graph shows Resistance vs Temperature for various voltages. The question asks you for a graph with different axis but I don't think they want voltage drop vs Rmax-Rmin. They want "voltage drop per grain boundary" vs the PTC (calculated over Rmax-Rmin).
 
Hi, I have this exact question, did you ever manage to solve the first part of the problem?
