PROBLEM 1: 14 volts is applied to the Wheatstone bridge as shown below. The purpose is to measure the value of a variable resistance sensor R₁. The resistance in arms 2 and 4 are fixed at R₂ = R₁ = 625 0. Variable resistance arm 3 is adjusted to R3 = 683 0 to achieve a condition of zero current through the galvanometer. What is the value for R₁? 15R² &{t= D
