A dc potentiometer, shown in figure below, is made by connecting fifteen $10\Omega$ resistors and a $10\Omega$ slide wire of length $\text{1000 mm}$ in series. The potentiometer is standardized with the current $I_p=10.0000 mA$. Balance for an unknown voltage is obtained when the dial is in position $11$ ($11$ numbers of the fixed $10\Omega$ resistor are included) and the slide wire is on the $ \text{234th mm}$ position. The unknown voltage (up to four decimal places) in $\text{volt}$ is __________.
