Question

Two resistances having coefficient of variation of resistivity \(α_1\) and \(α_2\) are having equal resistance. Equivalent temperature coefficient of resistivity in series and parallel combinations are:

• A. \(\frac{(α_1+ α_2)}{2}, α_1+ α_2\)
• B. \(α_1+ α_2, α_1+ α_2\)
• C. \(α_1+ α_2,\frac{ (α_1+ α_2)}{2}\)
• D. \(\frac{(α_1+ α_2)}{2}, \frac{(α_1+ α_2)}2\)

Answer 1

The Correct Option is D

The correct option is (D): \( \frac{(α_1+ α_2)}{2}, \frac{(α_1+ α_2)}{2} \)
