What is Anderson’s Bridge ?

Anderson’s Bridge Definition

Anderson’s Bridge is used to measure low-quality factor circuits by comparing known resistance and capacitance values.

Double Balance

It achieves double balance by fixing the capacitance and varying resistance.

High Accuracy

Known for its precision in measuring inductors ranging from micro Henry to several Henry.

Experimental Method

Set the signal frequency, adjust resistances, and use the derived formulas to find the unknown inductance.

Advantages

• It is very easy to obtain the balance point in Anderson’s bridge as compared to Maxwell bridge in the case of low-quality factor coils.

• There is no need for a variable standard capacitor is required instead of thin a fixed value capacitor is used.

• This bridge also gives accurate results for the determination of capacitance in terms of inductance

Disadvantages

• The equations obtained for the inductor in this bridge are more complex as compared to Maxwell’s bridge.

• The addition of capacitor junction increases complexity as well as the difficulty of shielding the bridge.
