Problem 7-2: Consider a deflection bridge arrangement as shown in the figure below: B A R1 ww 12 13 w R3 IA R2 ww RA D ww Em Rm C Hil E Voltage-sensitive Wheatstone bridge. 8X 个 Initially all four arms of the bridge are equal to 120 2. The resistance R₁ is a sensor, whose resistance changes with input. The supply voltage to the bridge is 9 V DC. If the resistance R₁ changes such that the bridge output is 0.5 V, determine the value of R₁ and the current flow through R1.
