The aim of my investigation is to see whether the resistance of a thermistor (a type of temperature sensitive resistor) is directly proportional to the temperature. Also I aim to see whether the length of the wires in the circuit affects the resistance. I'm anticipating that this experiment will be interesting and relatively challenging because a thermistor is a type of resistors whose resistance changes significantly when its temperature changes, consequently a slight variation in temperature can lead to a vast change in the resistance, therefore I have to be extremely accurate when calculating the temperature as a mistake or inaccurate reading on the thermometer will affect my results considerably. I will be using a bead thermistor with a negative temperature coefficient, which means the resistance decreases with an increase in temperature. The apparatus I will require will be a thermistor, a multimeter, two wires and crocodile clips. I will also...
