Ohms law,

$\overline{){\mathbf{V}}{\mathbf{=}}{\mathbf{i}}{\mathbf{R}}}$

In a balanced state,

V_{ab} = V_{ad}

i_{2}R_{3} = i_{1}R_{1}

i_{2}/i_{1} = R_{1}/R_{3}

V_{bc} = V_{dc}

Consider a Wheatstone bridge with some known resistances: R_{x} is 95 Ω, R_{1} is 25 Ω, and R2 is 185 Ω.

To what value, in ohms, must you adjust R_{3} to balance the Wheatstone bridge?

R_{3} =
