Problem 6.1   Source:   Problem elaborated by the author of the site.

Determine the value of R in the circuit shown in the Figure 06-01.1 so that the bridge is in equilibrium.

Solution of the Problem 6-1

Applying the knowledge seen in the theoretical part we know that for a Wheatstone bridge to remain in equilibrium the cross product between the resistors should be the same. So:

Then, it is easy to calculate the value of R, or:
