For an AC bridge working in 2000 Hz frequency, to obtain Null condition best detector is

Which of the following statements is/are correct about various AC bridges?

1). Anderson’s bridge is used for measurement of incremental inductance and incremental permeability.

2). Kelvin’s double bridge method is used for measurement of low resistance.

3). Maxwell’s inductance-capacitance bridge is not suitable for measurement of low Q-coil.

4). If the input signal contains different harmonics, then balancing of Wein’s bridge is not possible.

Consider the AC bridge shown in the figure below, with R, L and C having positive finite values. Which of the given below condition is correct?

In the bridge circuit shown, the capacitors are loss free, at balance, the value of C₁ in pF is

In Kelvin’s double bridge two sets of reading are taken when measuring low resistance, one with current in one direction and other with the direction of current reversed, this is done to
