Problem: Consider a Wheatstone bridge with some known resistances: Rx is 95 Ω, R1 is 25 Ω, and R2 is 185 Ω.To what value, in ohms, must you adjust R3 to balance the Wheatstone bridge?R3 = 

FREE Expert Solution

Ohms law,

V=iR

In a balanced state,

Vab = Vad

i2R3 = i1R1

i2/i1 = R1/R3 

Vbc = Vdc
