Which of the following statements is not true with respect to Maxwells...
Maxwell’s inductance bridge:
In Maxwell’s inductance bridge resistance is connected in parallel with the standard known capacitor. It is commonly used for the measurement of the Inductance of a coil having a Q value in the range (medium) of (1< Q < 10).
In Maxwell’s inductance bridge resistance is connected in parallel with the standard capacitor.
Notes:
1) A Maxwell bridge is a modification to a Wheatstone bridge used to measure an unknown inductance (usually of low Q value) in terms of calibrated resistance and inductance or resistance and capacitance
2) Maxwell-Wien Bridge, also known as Maxwell Inductance bridge can measure unknown inductance when a known capacitance in the bridge is given.
Equations of Maxwell-Wien bridge are:

Which of the following statements is not true with respect to Maxwells...
Equilibrium Equation in Maxwell's Bridge
Maxwell's bridge is a type of bridge circuit used for the measurement of inductance. The equilibrium equation in Maxwell's bridge is given by:
\[ R_1R_3 = R_2R_4 + L^2 \]
This equation is not dependent on the frequency of measurement. The equilibrium equation is based on the balance of the bridge circuit components at a specific frequency, which is usually the frequency at which the bridge is balanced for accurate measurements.
Why the Statement is Not True
The statement that the equilibrium equation in Maxwell's bridge is dependent on the frequency of measurement is not true. The equilibrium equation is determined by the values of the resistors and the inductor in the bridge circuit, and it is not influenced by the frequency at which the measurement is taken. The frequency of measurement may affect the sensitivity of the bridge circuit to changes in inductance, but it does not directly impact the equilibrium equation itself.
In summary, the equilibrium equation in Maxwell's bridge is independent of the frequency of measurement, and it is the balance of the components in the bridge circuit that determines the inductance value.
