Unformatted text preview: table DMM in a water bath of varying temperatures from 273K to 373K, the thermistor can be calibrated to function as a thermometer. The equation to find the resistance of a thermistor will be used to determine the constants B and R0 . THEORY The equation to find the resistance of a thermistor will be used to determine the constants B and R0. B B B R ln( 1 ) = T1 + T2 R2 R T T ln( 1 ) = B( 2 − 1 ) R2 T1T2 T1T2 R TT ⇒ B = ln( 1 )( 1 2 ) R2 T2 − T1 R = R0 E T −−−−−− R ⇒ R0 = B ET R1 R2...
