I appeared for an interview in May 2025, where I was asked the following questions.
- Q1. What do you understand by Ohm's Law and how would you apply it in a real-world scenario?
- Ans.
Ohm's Law relates voltage, current, and resistance in electrical circuits, crucial for designing and troubleshooting systems.
Ohm's Law states V = I * R, where V is voltage, I is current, and R is resistance.
In a circuit, if you know two of the three variables, you can calculate the third.
Example: If a resistor has a resistance of 10 ohms and the current flowing through it is 2 amps, the voltage across it is V = 2A * 10...
- Q2. How would you use MATLAB to simulate and analyze the behavior of a simple electrical circuit, such as half wave bridge rectifier ?
- Ans.
Use MATLAB to simulate a half wave bridge rectifier for analyzing voltage and current behavior.
Define circuit parameters: Set values for input voltage, load resistance, and diode characteristics.
Create a time vector: Use 'linspace' or '0:0.001:1' to define the time duration for simulation.
Model the circuit: Use MATLAB's Simulink or script to represent the rectifier using mathematical equations.
Run the simulation: Execu...
- Q3. What is the use of Matlab
- Ans.
MATLAB is a high-level programming language and environment for numerical computation, visualization, and programming.
Data Analysis: MATLAB is used for analyzing large datasets, such as in signal processing or image analysis.
Simulation: Engineers use MATLAB for simulating dynamic systems, like control systems or electrical circuits.
Algorithm Development: MATLAB allows for rapid prototyping of algorithms, making it easi...
