A silver wire has a resistance of `3.0 Omega` at `27.5^@C` , and a resistance of `3.8 Omega` at `100^@`C. Determine the temperature coefficient of resistivity of silver at `27.5^@`C.

Explanation

To find the temperature coefficient of resistivity (α) of silver at 27.5°C, we can use the formula:

\[ \alpha = \frac{R_2 - R_1}{R_1 \cdot (T_2 - T_1)} \]

Where:
- \( R_1 \) is the resistance at the initial temperature \( T_1 \)
