Bharatiya Rail Bijlee Company Diploma Apprentice Trainee Interview Questions, Process, and Tips

Introduction

Q1. How work is rectifier
Ans. 
A rectifier is an electronic device that converts AC to DC.
• Rectifiers are used in power supplies to convert AC voltage to DC voltage.

• They are commonly used in electronic devices such as radios, televisions, and computers.

• There are two types of rectifiers: half-wave and full-wave.

• Half-wave rectifiers only allow half of the AC waveform to pass through, while full-wave rectifiers allow the entire waveform to pass through.

Q2. Draw the rectifier diagram(ac ,dc)diagram
Ans. 
Rectifier diagram converts AC to DC by removing negative half cycles.
• Rectifier circuit consists of diodes and transformer.

• AC voltage is applied to the transformer which steps down the voltage.

• Diodes are used to remove the negative half cycles of the AC voltage.

• The output obtained is a pulsating DC voltage which can be smoothed using a filter circuit.

• AC rectifier diagram includes half-wave and full-wave rectifiers.

• DC re...read more

Q3. How work is multimeter.
Ans. 
A multimeter is a device used to measure electrical properties such as voltage, current, and resistance.
• A multimeter typically has a display screen, probes, and a dial or buttons to select the type of measurement.

• To measure voltage, the probes are connected to the circuit and the dial is set to the voltage range.

• To measure current, the multimeter is placed in series with the circuit and the dial is set to the current r...read more

Q5. What is Ohm's law explain.
Ans. 
Ohm's law states that the current through a conductor between two points is directly proportional to the voltage across the two points.
• Ohm's law is represented by the equation I = V/R, where I is the current, V is the voltage, and R is the resistance.

• It applies to conductors that are linear and have a constant temperature.

• Ohm's law is used in electrical engineering to calculate the current, voltage, or resistance in a ...read more

Q6. What is unit of temperature and pressure.
Ans. 
The unit of temperature is Kelvin, Celsius, and Fahrenheit. The unit of pressure is Pascal, Bar, and PSI.
• Temperature can be measured in Kelvin, Celsius, and Fahrenheit.

• Pressure can be measured in Pascal, Bar, and PSI.

• Kelvin is the SI unit of temperature.

• Pascal is the SI unit of pressure.

• Fahrenheit is commonly used in the United States.

• Bar is commonly used in Europe.

• PSI is commonly used in the United States for pressure

Q7. What is formula ofohm,s law
Ans. 
Ohm's law formula is V = IR, where V is voltage, I is current, and R is resistance.
• Ohm's law relates voltage, current, and resistance

• The formula is V = IR

• V is voltage, I is current, and R is resistance

• It can be used to calculate any one of the three variables if the other two are known
