1. Single-phase transformer has a magnetizing inductance of 250 mH and a core loss resistance of 300 Ω, referred to the primary side. When excited with a 230 V 50 Hz Sinusoidal supply the primary the power factor of the input current drawn, with secondary an open-circuited ____ (round off to two decimal places)
2. For the full bridge made of linear strain gauges with gauge factor 2 as shown in the diagram, R₁ = R₂ = R₃ = R₄ = 100 Ω at 0°C. All strain gauges are made of same material and exposed to the same temperature. While measuring a strain of 0.01 of a temperature of 50°C, the output V₀ in millivolt is ____ (rounded off to two decimal places)

1. The figure below shows an electrically conductive bar of square cross-section resting on a plane surface. The bar of mass of 1 kg has a depth of 0.5 m along the y-direction the bar and the surface is 0.1. Assume the acceleration due to gravity to be 10 m/s². The system faces a uniform flux density At time, t = 0, a current of 10 A is switched onto the bar and is maintained.
