I applied via Campus Placement and was interviewed before Oct 2021. There were 4 interview rounds.
Schottky diodes have low forward voltage drop, fast switching speed, and low reverse recovery time.
Low forward voltage drop reduces power loss and improves efficiency.
Fast switching speed makes them suitable for high-frequency applications.
Low reverse recovery time reduces switching losses and improves efficiency.
Schottky diodes are commonly used in power supplies, voltage clamping circuits, and RF applications.
Lenz's Law states that the direction of an induced current in a conductor is always such that it opposes the change in magnetic field that produced it.
When a magnet is moved towards a coil, a current is induced in the coil in such a direction that it opposes the motion of the magnet.
When a magnet is moved away from a coil, a current is induced in the coil in such a direction that it opposes the change in magnetic field...

Vector group is a code used to represent the phase displacement and connection type of transformer windings.
Vector group determines the phase shift between the primary and secondary windings of a transformer.
It also indicates the connection type of the windings, such as Y-Y, Y-Δ, Δ-Y, or Δ-Δ.
The vector group code consists of a combination of letters and numbers, such as YNd11 or Dyn11.
The first letter represents the pr...
Three phase IM works on the principle of rotating magnetic field produced by three phase AC supply.
Three phase AC supply is given to the stator winding which produces a rotating magnetic field.
The rotor winding is short-circuited and the rotating magnetic field induces a current in it.
The interaction between the stator and rotor magnetic fields produces torque which rotates the rotor.
The speed of the rotor is slightly ...
Starters in 3-ph Im
Starters are used to control the starting and stopping of 3-phase induction motors.
Direct-on-line (DOL) starters are the simplest type of starters.
Soft starters and variable frequency drives (VFDs) are more advanced types of starters.
Starters protect the motor from overloading and overheating.
Starters also provide a means of reversing the motor's direction of rotation.
