±0.1%. This means that the resistance values of the ratio arms can deviate from their nominal values by a maximum of ±0.1%. For example, if the nominal resistance value of a ratio arm is 1000 ohms, its actual resistance value can be between 990 ohms and 1010 ohms.

The accuracy of the Wheatstone bridge as a whole depends on the accuracy of all its components, including the ratio arms, the galvanometer, and the power supply. The overall accuracy of the bridge can be improved by carefully selecting and calibrating these components.

In practice, Wheatstone bridges are commonly used for measuring small changes in resistance, such as those produced by strain gauges or thermistors. The accuracy of the bridge is critical in such applications, as small errors in resistance measurement can lead to significant errors in the final result.
