Memory-based Questions Asked in GATE IN 2021 Paper

  1. A infinitely long line, with uniform positive charge density, lies along the z-axis. In cylindrical coordinates (r, ϕ, z), at any point not on the z-axis, the direction of the electric field is
  2. Consider a system with transfer function A unit step function μ(t) is applied to the system, which results in an output y(t)

        If e(t) = y(t) = y(t) – μ(t), then line  is _______


  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)
