For metals, the temperature coefficient of resistance is:
- A
Infinity
- B
Negative
- C
Positive
- D
Zero
The coefficient of temperature for resistance in metals is positive.
This option is incorrect, as resistance of metals increases as temperature increases due to the oscillations of positive metal ions.
This option is incorrect, as resistance of metals increases as temperature increases due to the oscillations of positive metal ions. Therefore the coefficient cannot be negative.
