Formulas:
1. Zero-power Resistance of Thermistor: R = R0 exp[B (1/T - 1/T0)] ............(1)
2. B-Constant: B = ln(R/R0) / (1/T - 1/T0) ............(2)
3. Thermal Dissipation Constant: P = C (T2 - T1) ..................(3)
Where:
- R: Resistance in ambient temperature T (K)
- R0: Resistance in ambient temperature T0 (K)
- B: B-Constant of Thermistor
- P: Electric power spent (mW)
- C: Thermal Dissipation Constant
- T1: Ambient temperature
- T2: Thermistor temperature
