Question 5

Can you explain Ohm’s Law and its significance?
Answer:
Ohm’s Law states that the current flowing through a conductor between two points is directly proportional to the voltage across the two points and inversely proportional to the resistance between them (V=IR). Its significance lies in being a fundamental principle for analyzing and designing electrical circuits, allowing us to calculate voltage, current, or resistance.

Question 6

Describe a time you faced a technical challenge and how you overcame it.
Answer:
During my final year project, we encountered an unexpected power fluctuation issue in our prototype that was difficult to diagnose. I systematically checked each component, reviewed the circuit diagrams, and used an oscilloscope to pinpoint a faulty capacitor. This allowed us to quickly replace it and restore stable operation.

Question 7

What simulation software are you familiar with, and how have you used it?
Answer:
I am proficient in using SPICE for analog circuit simulation and MATLAB/Simulink for control systems and signal processing. For instance, I used Simulink to model and analyze the stability of a feedback control loop for a motor speed control system in a university lab.
