alleryThe dimension of the temperature coefficient alpha is:
AInverse resistance
BInverse capacitance
CInverse conductance
DInverse temperature
Answer & Solution
Correct answer: D. Inverse temperature
1. Alpha multiplies a temperature difference in the formula.
2. Its dimension is temperature raised to the power minus one.
3. So the correct answer is inverse temperature.
