Anderson's bridge is essentially anull-method and . The ratio of the measured value of the mutual inductance to the theoretical value is defined as coupling. To measure self inductance of a coil using Anderson's Bridge. THEORY: When Anderson Bridge is balanced in the sound in head phone or deflection. The Anderson's Bridge is an A.C bridge used to measure the self-inductance of the coil. It enables to measure the inductance of a coil using a standard capacitor and resistors. It does not require repeated balancing of the bridge.

In Anderson bridge, the unknown inductance is compared with the standard fixed capacitance which is connected between the two arms of the bridge.
And the other three arms consist the purely resistive arms connected in series with the circuit. The static capacitor and the variable resistor are connected in series and placed in parallel with the cd arm. The voltage source is applied to the terminal anderson bridge theory and c.

It also gives the dynamics of special type of non-linear systems. Electric Circuits Virtual Lab Pilot An electric circuit is composed of individual electrical components such as resistors, inductors, capacitors etc to trace the current that flows through it.
The combination of electrical components can perform various simple and anderson bridge theory electrical operations.
Advanced Mechanics Virtual Lab The laboratory is concerned with the issues anderson bridge theory advanced dynamics in mechanical systems dealing with describing motions, as well as the causes of motion.
Optics Virtual Lab Optics is the study of the behavior and properties of light, including its interactions with matter and the construction of instruments that use or detect it.

Optics usually describes the behavior of visible, ultraviolet, and infrared light. Now adjust r1 and r such that phones gives a minimum sound.
Anderson bridge theory the values of r1 and r obtained after these adjustments with the help of multimeter. Use the formula that we have derived above in order to find out the value of unknown inductance.

The experiment can be repeated with the different value of standard capacitor. Phasor Diagram of Anderson's Bridge Let us mark the voltage drops across ab, bc, cd and ad as e1, e2, e3 and e4 as shown in figure anderson bridge theory.
Here in the phasor diagram of Anderson's bridge, we have taken i1 as reference axis. Now ic is perpendicular to i1 as capacitive load is connected at ec, i4 and i2 are lead by some anderson bridge theory as shown in figure.
