Q3. Need and use of filter capacitor in rectifier circuit
Ans. 
Filter capacitor in rectifier circuit is used to smooth out the output voltage by reducing ripple and noise.
• Filter capacitor stores and releases electrical energy to reduce voltage ripple in rectified output

• It helps in converting pulsating DC output of rectifier into a smoother DC output

• Commonly used in power supplies and electronic devices to improve stability and reduce interference

• Examples include smoothing capacito...read more

Q1. What is the principle of transformer
Ans. 
The principle of a transformer is based on electromagnetic induction.
• Transformers work on the principle of transferring electrical energy between two or more coils through electromagnetic induction.

• They consist of two coils, known as the primary and secondary coils, which are wound around a common magnetic core.

• When an alternating current (AC) flows through the primary coil, it creates a changing magnetic field around ...read more

Q2. What is inverter and its types?
Ans. 
An inverter is a device that converts direct current (DC) to alternating current (AC).
• Inverters are commonly used in solar power systems to convert DC power from solar panels to AC power for use in homes and businesses.

• There are three main types of inverters: square wave, modified sine wave, and pure sine wave.

• Square wave inverters are the simplest and least expensive, but they produce a choppy output waveform that may...read more

Q2. 1)swap numbers 2) sum of diagonals of matrix
Ans. 
Answering two technical questions asked in a Graduate Engineer Trainee interview.
• To swap two numbers, we can use a temporary variable or arithmetic operations.

• To find the sum of diagonals of a matrix, we can use a loop to iterate through the rows and columns.

• For a square matrix, the sum of the main diagonal is the sum of elements at (i, i) position and the sum of the secondary diagonal is the sum of elements at (i, n-i

Q1. What is polymorphism and method overriding
Ans. 
Polymorphism is the ability of a single function or method to operate on different types of data. Method overriding is when a subclass provides a specific implementation of a method that is already provided by its parent class.
• Polymorphism allows different classes to be treated as instances of a common superclass.

• Method overriding is a feature that allows a subclass to provide a specific implementation of a method that...read more

Q2. What is encaplusulation and explain it with an example
Ans. 
Encapsulation is the concept of bundling data and methods that operate on the data into a single unit.
• Encapsulation helps in hiding the internal state of an object and only exposing the necessary functionalities.

• It allows for better control over the data by preventing direct access from outside the class.

• An example of encapsulation is a class in object-oriented programming that has private variables and public methods
