The discussion focuses on calculating the resistivity of a wire wound around a cylinder, utilizing the formula R = ρl/A, where R is resistance, ρ is resistivity, l is the length of the wire, and A is the cross-sectional area. Participants emphasize the importance of considering the 200 coils of wire and suggest starting with a diagram to visualize the setup. Effective resistance is also discussed, defined as the reciprocal of resistance (1/R). The conversation highlights the necessity of demonstrating effort in problem-solving, particularly in academic contexts.
PREREQUISITESStudents in physics or electrical engineering, educators teaching circuit theory, and anyone involved in practical applications of electrical resistance calculations.
You can start with a diagram. It is mandatory here to show some efforts on your own.curiosity colour said:
I think it's should look like this, with the wire wound closely together( please excuse my horrible drawing).cnh1995 said:
