In the bridge circuit shown, the capacitors are loss free. At balance, the value of capacitance C₁ in microfarad is ________.

A strain gauge forms one arm of the bridge shown in the figure below and has a nominal resistance without any load as $$\,{R_s} = 300\Omega .$$ Other bridge resistance are $$\,{R_1} = {R_2} = {R_3} = 300\Omega .\,\,$$ The maximum permissible current through the strain gauge is $$20$$ $$mA.$$ During certain measurement when the bridge is excited by maximum permissible voltage and the strain gauge resistance is increased by $$1$$% over the nominal value, the output voltage $${V_0}$$ in $$mV$$ is

The Maxwell's bridge shown in the fig. is at balance, the parameters of the inductive coil are
