View answer

A thermopile having a resitance of 100 Q and consisting of 20 copper-constantan thermocouples is used to measure temperature difference between two points. The temperature of the first point measured separately is 25°C. EMF generated measured by a voltage measuring device having an internal resistance of 1000 Q is 1.47 mV. E MF-temperature relationship for copper-constantan thermocouple with reference junction at 0° is as follows. (2001)Determine the temperature difference between the two points after applying a correction for loading effect in the measurement of the EMF. Correct answer is '90.90'.

A 220 V DC series motor runs drawing a current of 30 A from the supply. Armature and field circuit resistances are 0.4 and 0.1 respectively. The load torque varies as the square of the speed. The flux in the motor may be taken as being proportional to the armature current. To reduce the speed of the motor by 50% the resistance in ohms that should be added in series with the armature is _________. Correct answer is between '9.5,12'. Can you explain this answer?
