Homework Help Overview
The problem involves calculating the resistance of a bobbin at 50 degrees Celsius given its resistance at 0 degrees Celsius and a thermal constant. The original resistance is stated as 3.35 ohms, and the thermal constant is 0.0037.
Discussion Character
- Exploratory, Assumption checking
Approaches and Questions Raised
- Participants discuss the application of the formula R1=R0[1+alpha(t-t0)] to find the resistance at a higher temperature. There is uncertainty regarding the rounding of the final answer and whether intermediate calculations at other temperatures, such as 20 degrees Celsius, should be performed.
Discussion Status
Some participants confirm the calculations provided by the original poster, while others express confusion over the discrepancy between their results and the answer in the textbook. The discussion is ongoing, with participants exploring the implications of rounding and the accuracy of their calculations.
Contextual Notes
There is a noted difference between the calculated resistance and the value provided in the textbook, leading to questions about rounding and the correctness of the formula application.
