hey ill be quick about this, i really need help with a potential divider circuit. basically i have a resistor and a thermistor in series. 5 v input, and the values given for the thermistor are in volts, i need them in ohms. so i need to use the voltage across the thermistor, the total input voltage and the resistance of the resistor to find the resistance of the thermistor ata temperature. can anyone help?

Hi

You can use the formula to find the resistance of the thermistor.

X / R+X * 5(volts) = V

Where R is the resistance of the resistor and V is the voltage across the thermistor.

Then solve for X which is the resistance of the thermistor.
