The equations under conditions of balance for a bridge measuring resistance R1, and inductance L1 of a choke coil are
In order to achieve convergence of balance
In measurement of resistance by “Carey Foster bridge” no error is introduced due to
A capacitance comparison bridge as shown in figure below is used to measure a capacitive impedance at a frequency of 2 kHz. The bridge constants at balance are:
The equivalent series circuit of the unknown impedance will be represented as:
A Wien bridge circuit consists of the following:
The frequency of the circuit is
An ac bridge uses a detector in the form of
Maxwell’s bridge is used to measure Q-factor in the range
Anderson bridge is used to measure unknown
Hay’s bridge is used to measure an inductance of
