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

A single-phase transformer has no-load loss of 64 W, as obtained from an open circuit
test. When a short-circuit test is performed on it with 90% of the rated
currents flowing in its both LV and HV windings, he measured loss is 81 W. The
transformer has maximum efficiency when operated at

The following arrangement consists of an ideal transformer and an attenuator
which attenuates by a factor of 0.8. An ac voltage VWX1 = 100V is applied across
WX to get an open circuit voltage VYZ1 across YZ. Next, an ac voltage VYZ2 =100V is
applied across YZ to get an open circuit voltage VWX2 across WX. Then,
$$\frac{V_{YZ1}}{V_{WX1}}$$, $$\frac{V_{WX2}}{V_{YZ2}}$$
are respectively,
