  • Ans. 

    Current is the flow of electric charge, measured in Amperes, while voltage is the force that drives the current, measured in Volts.

    • Current is the rate of flow of electric charge in a circuit

    • Voltage is the electrical potential difference that drives the current

    • Current is measured in Amperes (A)

    • Voltage is measured in Volts (V)

    • Ohm's Law states that V = I * R, where V is voltage, I is current, and R is resistance

    • Allows for continuous rotation without tangling wires

    • Commonly used in electromechanical systems like motors, generators, and wind turbines

    • Consists of stationary brushes and rotating conductive rings

    • Helps in transmitting power, data, and signals across rotating interfaces

  • Answered by AI
  • Q2. What is oer unit slip
  • Ans. 

    Unit slip is the difference between synchronous speed and rotor speed in an induction motor.

    • Unit slip is expressed as a fraction or percentage.

    • It is used to calculate the rotor speed of an induction motor.

    • Unit slip is necessary for determining the torque and efficiency of the motor.

    • For example, if the synchronous speed of a motor is 1800 RPM and the rotor speed is 1750 RPM, the unit slip would be 0.0278 or 2.78%.

Interview Preparation Tips

Interview preparation tips for other job seekers - This interview was a technical one but was majorly a stress test. It lasted for about 1 hour 10 minutes. The interviewer wanted to test both my knowledge and communication skills. Most of the questions asked to me were related to my B.Tech curriculum i.e. computer science related topics. He stressed a lot on the basics related to my project topic. Luckily I was able to answer most of the questions correctly. I tried to answer each question with examples and also used props on the table (like pens, paperweights, pen stands etc.) to explain my theories. It was my first offcampus interview, and I think I did pretty well for a fresher. You need to stay calm and should apply presence of mind. Please go through the job description thoroughly word-by-word and recheck your resume to ensure that you are a best-fit for the position.
