$\frac{dy}{dx}=2x-y,y\left(0\right)=1$

A three-phase, 50 Hz, 4-pole induction motor runs at no-load with a slip of 1%. With full load, the slip increases to 5%. The % speed regulation of the motor (rounded off to 2 decimal places) is

Currents through ammeters A₂ and A₃ in the figure are 1∠10° and 1∠70°, respectively. The reading of the ammeter A₁ (rounded off to 3 decimal places) is _____ A.

The Thevenin equivalent voltage, Vₜₕ, in V (rounded off to 2 decimal places) of the network shown below, is ________

A double pulse measurement for an inductively loaded circuit controlled by the IGBT switch is carried out to evaluate the reverse recovery characteristics of the diode, D, represented approximately as a piecewise linear plot of current vs time at diode turn-off. Lₚₐᵣ is a parasitic inductance due to the wiring of the circuit, and is in series with the diode. The point on the plot (indicate your choice by entering 1, 2, 3 or 4) at which the IGBT experiences the highest current stress is _____
