Bridge Anderson
[1016]

anderson Bridge for Self-inductance
this Bridge Method is More Complicated Than Those Which have Been Described So Far. the Bridge Has Got Following Main Features :
p = Non-inductive Resistance of 1000 Ohms.
q = Non-inductive Resistance of 1000 Ohms.
r = Non-inductive Resistance of 1000 Ohms.
s = a Variable Non-inductive Resistance in the Form of 3-decades of 10 X 1, 10 X 10 and 10 X 100 Ohms. this Resistance also Includes the Resistance of Self-inductance L Which is also Connected in the Same Arm.
m = a Non-inductive Variable Resistance of 3 Decades of 10 X10, 10 X 100 and 10 X 1000 Ohms.
c = a Standard Capacitance Provided in the Bridge in the Form of a Single Decade of 10 X 0.01 Mfd.
*an Audio Frequency Oscillator of 1 Kc/s and a Variable Output of 10 Volts is Used as a Source of Supply.
a Pair of Headphone of Good Sensitivity is Used as a Detector in the Bridge Network.
