Experiment: STUDY THR VARIATION OF RESISTANCE OF A THERMISTER” WITH TEMPERATURE Object: To study the effect of temperature (max. of 100 °C) on a thermistor (negative temperature coefficient). Ref[http://tap.iop.org/electricity/resistance/110/page_45969.html] Apparatus: • • • • • • • A given thermistor (negative temperature, coefficient) Power supply, 5 V, DC Ohmmeter Mercury thermometer (-10C to +110 C) Beaker (250 ml) Heating arrangement Stand Formula: Procedure: i) ii) iii) iv) v) vi) vii) viii) ix) No formula is used Clean all the terminals of wires with sandpaper. Make connections as shown in the figure Dip only the thermistor in a beaker containing normal cold water having thermometer in it. Supply power to the circuit Take readings of temperature and resistance. Place a heating source below the beaker. Now slowly heat the water and note down the current in it corresponding to changing temperatures ‘T’ (say 10, 20, 30… °C) in regular steps. Finally, ..
