In
general there will be currents flowing across all the resistors as well as a
current Ig through G Of special interest, is the case of a balanced bridge
where the resistors are such that Ig = 0 We can easily get the balance
condition, such that there is no current through G In this case, the
Kirchhoff’s junction rule applied to junctions D and B (see the figure)
