JSW Steel Diploma Apprentice Trainee Interview Questions and Answers

An aptitude test is a standardized exam that measures a person's skills, abilities, and potential to succeed in a specific role or field. Aptitude tests are used in schools, by employers, and to help people make career decisions.
What aptitude tests measure
Cognitive abilities: Logical reasoning, verbal comprehension, numerical ability, and problem-solving skills
Special abilities: Clerical speed, mechanical reasoning, and professional potential
How aptitude tests are used
Schools: To determine if students are inclined toward advanced placement classes or specific areas of study
Employers: To assess a potential candidate's strengths and weaknesses
Career counseling: To help people make career decisions
Diagnostic purposes: To identify training needs and development opportunities
How aptitude tests are administered
Online or in person
Multiple-choice tests, real-life work simulations, or group activities
Usually have time limits
Examples of aptitude tests Scholastic Assessment Test (SAT), American College Testing Exam (ACT), and Differential Aptitude Test (DAT).

Definition
A case study is a detailed analysis of a real-world situation, person, group, or event. Case studies are used to understand the broader processes and features at work by studying a specific subject in its natural setting.
Uses
Case studies are used in many fields, including business, education, medicine, psychology, and social work. In business, case studies can help identify issues and conduct further research. In marketing, case studies can be used to convince consumers with real-world stories of customer experiences.
Research method
Case studies are considered "naturalistic" because the subjects are studied in their natural context. Unlike experiments, where researchers control and manipulate situations, case studies are based on observations.
Format
A case study typically includes a headline, snapshot, client introduction, problem, solution, results, and conclusion.
Examples
Some famous case studies include John Martin Marlow's case study on Phineas Gage and Sigmund Freud's case studies, Little Hans and The Rat Man.

Q1. What is motor and sigal phase and three phase motar difference
Ans. 
A motor is a device that converts electrical energy into mechanical energy, while a signal phase motor operates on single phase power and a three phase motor operates on three phase power.
• Motor is a device that converts electrical energy into mechanical energy

• Single phase motor operates on single phase power

• Three phase motor operates on three phase power

• Three phase motors are more efficient and have higher power output

Q5. What is tha current law
Ans. 
Ohm's Law states that the current flowing through a conductor is directly proportional to the voltage applied across it, and inversely proportional to the resistance of the conductor.
• Current (I) = Voltage (V) / Resistance (R)

• It helps in calculating the current flowing through a circuit based on the voltage and resistance values.

• It is represented by the formula I = V/R.

• Ohm's Law is fundamental in understanding and analy
