INTRODUCTIONA thermistor is a type of resistor used to measure temperature changes, relying on the change inits resistance with changing temperature. The thermistor is a combination of the words thermaland change. Thermistors are made of semiconductor materials such as the metallic compoundsincluding oxides such as manganese, copper, cobalt, and nickel, as well as single-crystalsemiconductors silicon and germanium. Thermistors can be classified on the basis of the constantk. when K is positive, the resistance increases with increasing temperature, and the device iscalled a positive temperature coefficient, PTC and when it is negative, the resistance decreaseswith increasing temperature and the corresponding device is the negative temperature coefficient.CIRCUIT SPECIFICATIONSThermistor 44007Temperature Range-100C to +200COutput -1.0 V to +2.0VOutput Tolerance±5mVType of OpAmp741DC Powers±12V±100mVType of amplifier in your circuitInverting amplifierTolerance of resistance due to aging and environment variations±1% of normal valueAccuracy of the Thermistor±1% of normal valueReference Temperature: 250CFigure 1 Non-Inverting Operational Amplifier opamp-741QUESTION 1Using the Multisim Software, the circuit was obtained as shown in the diagram below,
