Q1. Design an Astable Multivibrator and explain its functioning
Ans. 
An Astable Multivibrator is a type of oscillator circuit that generates a continuous square wave output.
• Consists of two transistors cross-coupled through capacitors and resistors

• No stable state, continuously switches between high and low states

• Capacitors charge and discharge alternately, creating oscillations

• Commonly used in applications like signal generators, LED flashers, and tone generators

Q2. Draw the VI characteristics of a pn junction diode and explain the graph
Ans. 
The VI characteristics of a pn junction diode show the relationship between voltage and current flowing through the diode.
• The graph shows a non-linear relationship between voltage and current, with forward and reverse bias regions.

• In forward bias, the diode conducts current easily with a small voltage drop, while in reverse bias, it blocks current flow until breakdown voltage is reached.

• The knee voltage in the forward ...read more

Q4. What are the types of transformer losses
Ans. 
Types of transformer losses include copper losses, iron losses, and stray losses.
• Copper losses: Also known as I^2R losses, occur in the copper windings of the transformer due to resistance.

• Iron losses: Also known as core losses, occur in the transformer core due to hysteresis and eddy currents.

• Stray losses: Occur due to leakage flux and imperfect magnetic coupling between the windings.

• Examples: An example of copper los...read more

Q5. Working principle of generator
Ans. 
A generator works on the principle of electromagnetic induction to convert mechanical energy into electrical energy.
• Generators use a magnetic field and a conductor to create a flow of electrons, generating electricity.

• When the conductor moves through the magnetic field, it induces a current in the conductor.

• This current is then collected and transferred through wires to power electrical devices.

• Examples of generators i...read more
