Thermal Expansion - Find Current for Iron, Aluminium & Copper Coils

Click For Summary
SUMMARY

The discussion focuses on determining the current required to thermally expand coils made of iron, aluminum, and copper. A key suggestion is to search for the resistivity values of these metals, as they are essential for calculating the resistance of the wire used in the coils. The concept of modeling a non-ideal inductor as an ideal inductor in series with a resistor is also highlighted, emphasizing the importance of understanding resistance in this context.

PREREQUISITES
  • Understanding of electrical resistance and resistivity
  • Familiarity with inductors and their characteristics
  • Basic knowledge of thermal expansion principles
  • Ability to perform calculations involving current and resistance
NEXT STEPS
  • Research the resistivity values of iron, aluminum, and copper
  • Learn about the thermal expansion coefficients of these metals
  • Explore the concept of non-ideal inductors in electrical circuits
  • Study Ohm's Law and its application in calculating current
USEFUL FOR

Electrical engineers, physics students, and anyone involved in designing or analyzing coil systems for thermal applications.

Hi guys,

I need to find out what current i need to expand different type of coils. eg iron, aluminium, copper, etc. Is there a website that can give me this information? I tried searching but no luck.

Thx

Try searching for the resistivity of those metals. A non ideal inductor (coil) can be modeled as an ideal inductor (zero resistance) in series with a resistor equal in value to the resistance of the length of wire.
