Q1. Capacitor behaviour in ac/dc circuit?
Ans. 
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

Q2. Diode working principle and breakdown mechanism ?
Ans. 
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

Q3. What is thevnins theorem?
Ans. 
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...read more

Q4. Stabilloty analysis in control system?
Ans. 
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...read more
