Q2. Difference between capacitor and inductor
Ans. 
Capacitors store electrical energy in an electric field, while inductors store energy in a magnetic field.
• Capacitors store energy in the form of an electric field, while inductors store energy in the form of a magnetic field.

• Capacitors are used to store and release energy quickly, while inductors are used to resist changes in current flow.

• Capacitors are commonly used in filtering and tuning circuits, while inductors ar...read more

Q2. What is thevenion theorem
Ans. 
Thevenin's theorem states that any linear electrical network can be replaced by an equivalent circuit comprising a voltage source and a series resistor.
• The theorem is used to simplify complex circuits into simpler ones.

• It is based on the principle of superposition.

• The equivalent circuit can be used to calculate the voltage and current in any part of the original circuit.

• The theorem is named after French engineer Léon C...read more

Q3. What is sampling theorem
Ans. 
Sampling theorem is a mathematical concept that states a continuous signal can be accurately represented by a discrete signal.
• It is also known as Nyquist-Shannon sampling theorem.

• It is used in digital signal processing and communication systems.

• The theorem states that the sampling rate must be at least twice the highest frequency component in the signal.

• If the sampling rate is too low, aliasing can occur, which results...read more
