I need to solve the task shown on the picture.
The first part is to calculate the temperature (in °C) from the NTC when Uv = 2V is. This means Iv is infinite.
The given Values are: Uq = 12V, R1 = 100Ohm, R2 = 200Ohm, R3 = 300Ohm
NTC: Rn = 1kOhm, b = 2000Kelvin, Tn = 293K
I tried using the formula: Uv = Uq((R2/(R1+R2)) - (R3/(R3+NTC))) and got 600Ohm for the NTC. After using it in the forumla for calculating an NTC I got only 81.85 degrees Celsius.
Can someone help me?
