Question 2 1. Discussthe Seebeck effect. 2. When the cold junction of a thermocouple thermometer is at 10°C and the hot junction at 80 °C, the millivoltmeter shows a deflection of 3.5 mV towards the left. The hot junction is now put in an unknown temperature while maintaining the cold junction at 10°C. The millivoltmeter now shows a deflection of 4.7 mV towards the left. Calculate the unknown temperature.

PLEASE answer the all of Question two
Question 1 1. Use suitable sketches to describe the principle of operation of a resistance strain gauge. 2. Calculate the strain experienced by a rod of length 2m subjected to a force that causes a change of resistance of 0.2x 102 in the gauge Wheatstone bridge circuit. The strain gauge has gauge factor of 1.5 and the resistivity of the Wheatstone bridge circuit wires is 1.83×10* ohm-meter having a cross-sectional area 0.03m² and length 0.15m. | Question 2 1.
