Wheatstone bridge

The device's primary component is an electrical measuring instrument called a Wheatstone bridge, which measures the subject's galvanic skin response.

The Wheatstone bridge illustrates the concept of a difference measurement, which can be extremely accurate.

This resistance change, usually measured using a Wheatstone bridge, is related to the strain by the quantity known as the gauge factor.

Its operation is similar to the Wheatstone bridge except for the presence of additional resistors.

Which is equivalent to the Wheatstone bridge.

One form of Wheatstone bridge is shown in the illustration.

Measuring resistance was done by use of a device called a Wheatstone bridge.

Most a.c. bridges are similar in form to the Wheatstone bridge for measuring resistance described in section 3.9.

Combustible gases burn in the presence of the hot wire, thus increasing the resistance and disturbing a Wheatstone bridge, which gives the reading.

The strips formed two branches of a Wheatstone bridge which was fitted with a sensitive galvanometer and connected to a battery.
