Ntc b value

In this region the device has a small negative temperature coefficient. At the Curie point temperature, the dielectric constant drops sufficiently to allow the formation of potential barriers at the grain boundaries, and the resistance increases sharply with temperature. At even higher temperatures, the material reverts to NTC behaviour B value is the constant value of NTC thermistor, That is, NTC thermistor chip (semiconductor ceramic) after high temperature sintering, Forming a negative temperature coefficient material having a resistivity, Different formulations and sintering temperature of the formation of the resistance, have different B value, So called the material constant

Then the B value will define the thermistors resistive value at the first temperature or base point, (which is usually 25 o C), called T1, and the thermistors resistive value at a second temperature point, for example 100 o C, called T2. Therefore the B value will define the thermistors material constant between the range of T1 and T2 \$\begingroup\$ I know the question used B value without defining it, which is on the OP. But doing the same in your answer is now on you. I have never seen something in a thermistor datasheet called a B value that was dimensionless, so your answer lacks meaning without a proper definition
