I applied via Campus Placement and was interviewed before Nov 2023. There were 2 interview rounds.
It was MCQ based test which involves basic Aptitude questions on the topics like data interpolation, permutation combination and also involved basic questions over Analog and digital electronics system, control system and communication system which usually we learn in 2nd year of the engineering
Capacitors store and release electrical energy in AC/DC circuits.
Capacitors block DC current while allowing AC current to pass through
Capacitors store energy in an electric field when connected to a DC circuit
Capacitors release stored energy in the form of AC current when connected to an AC circuit
A diode is a semiconductor device that allows current to flow in one direction only. Breakdown can occur due to excessive voltage or current.
Diode allows current to flow in one direction due to its PN junction
Breakdown can occur due to excessive voltage (avalanche breakdown) or excessive current (thermal breakdown)
Zener diodes are designed to operate in breakdown region for voltage regulation
Thevenin's theorem states that any linear electrical network can be replaced by an equivalent circuit consisting of a single voltage source and a single series resistor.
The theorem simplifies complex circuits into simpler equivalent circuits for analysis.
It helps in determining the voltage and current across any component in the network.
The equivalent Thevenin voltage is the open-circuit voltage at the terminals of the...
Stability analysis in control systems involves assessing the stability of a system's behavior over time.
Stability analysis is crucial in ensuring that a control system operates predictably and reliably.
Methods such as root locus, Bode plot, and Nyquist plot are commonly used for stability analysis.
Stability criteria, such as the Nyquist stability criterion or Routh-Hurwitz criterion, are used to determine system stabil...
