SUMMARY

The discussion focuses on rearranging the resistance formula R = (resistivity x length) / 4(d/2)² into the linear form Y = Mx + C. Participants clarify that resistance (R) is the dependent variable, while the diameter of the wire (d) is also treated as a dependent variable. A suggested approach involves taking the reciprocal of both sides to simplify the equation, which allows for further manipulation to achieve the desired linear format.

PREREQUISITES
  • Understanding of basic algebraic manipulation
  • Familiarity with the concept of resistance in electrical circuits
  • Knowledge of resistivity and its role in resistance calculations
  • Basic understanding of linear equations and their components (Y, M, x, C)
NEXT STEPS
  • Study the principles of resistivity and its impact on electrical resistance
  • Learn about algebraic rearrangement techniques for equations
  • Explore the relationship between diameter and resistance in wire calculations
  • Investigate the application of linear equations in physics and engineering contexts
USEFUL FOR

Students in physics or engineering, electrical engineers, and anyone interested in understanding the mathematical relationships in electrical resistance calculations.

how do you rearrange the formula of resistance = (resistivity x length) / 4(d/2)squared to a y=mx+c equation


resistance (R) = (resistivity x length) / 4(d/2)squared
where resistance is the dependent variable, diameter of wire (d) is the dependent variable


what i got was 2 times square root R = (2 x resisitivity x length) x 1/d

help would be appreciated! :D

Since the d2 begins in the denominator, why not first take the reciprocal of both sides? That'll move the d2 to the numerator. Then apply the square root.
 


thanks :) i was really stuck :P
thanks again!
