Explanation

What is the relation between α and β for a thermistor?

a: β = -α / T² Explanation

Explanation

b: α = β / T² Explanation

Explanation

c: α = -β / T² Explanation

Explanation

d: β = α / T² Explanation

Explanation

Electrical resistance of a thermistor as a function of temperature is given by

R = R_0 \exp(\alpha (\frac{1}{T} - \frac{1}{T_0}))

Explanation

R = \beta T

Explanation

R = \alpha T

Explanation

R = R_0 \exp(\beta (\frac{1}{T} - \frac{1}{T_0}))
