The Owen Bridge


The arrangement of owen bridge is shown in figure 1. In this method, also, the inductance is determined in terms of resistance and capacitance. This method has, however, the advantage of being useful over a very wide range of inductance with capacitors of reasonable dimensions.

Balance condition is

Z1Z3 = Z2Z4

Here,

Separating the reals and imaginaries, we get

Since ω does not appear in the final balance equations, hence the owen bridge is unaffected by frequency variations and wave-form.
