36: The condition for the bridge balance is: (R1/R2) = (R3/R4). Thus, (120/100) = (220/R4), which gives R4 = 183.33 ohms. The 1K pot is at 50% level i.e. 500 ohms. Thus you need to decrease the resistance. For this, you turn the pot less-than-50%.
37: The condition for the bridge balance is: (R1/R2) = (R3/R4). Thus, (120/220) = (330/R4), which gives R4 = 605 ohms. The 1K pot is at 50% level i.e. 500 ohms. Thus you need to increase the resistance. For this, you turn the pot more-than-50%.
NOTE: The voltage supply does not affect the bridge balance condition.

A resistive temperature sensor Rv (calibration curve shown below) is used to measure the temperature of a process using Wheatstone bridge (Fig. 1). When the bridge is balanced, EO = OV. Then the Ry is inserted into a process whose temperature is 100C. Assume Ei = 10V, R1 = R2 = R3 = 4k12. 1. At which temperature the bridge is balanced? How much is EO at balanced mode? 2. Find the bridge output voltage E, a 3-significant figure voltmeter...
