LCD Anderson Bridge

Anderson Bridge for Self InductanceThis bridge method is more complicated than those which have been described so far. The bridge has the following characteristics : p = consists of three ratio dials of 10, 100 & 1000 ohms. q = consists of three ratio dials of 10, 100 & 1000 ohms. r = non-inductive resistance of 1000 ohms (fixed value). s = a variable non - inductive resistance in the form of 3 decades of 1 x 10, 10 x 10 & 100 x 10 ohms. This resistance also includes the resistance of self - inductance 'l' which is also connected to the same arm. m = a non-inductive variable resistance of 3 decades of 10 x 10, 100 x 10 &1000 x 10 ohms. c = standard capacitance provided in the bridge in the form of a single decade of 10 x 0. 01 mfd. Supplied with unknown inductance whose value is to be calculated.
