Consider the constant-voltage bridge shown in Figure 4.31a.

Suppose that the bridge is balanced with the resistors set according to

438_b516a6bd-8e7e-4e3e-91b4-4053a2c5d7b9.png

Now, if the active element R1 increases by δR1, what is the resulting output of the bridge?

For what value of the resistance ratio p, would the bridge sensitivity be a maximum? Show that this ratio is almost equal to 1.
