Aditya Birla Group Electrical Design Engineer Interview Questions and Answers

Q1. What is armature
Ans. 
Armature is the rotating part of an electrical machine, such as a motor or generator, which carries the current and produces the mechanical power.
• Armature is the part of an electrical machine that interacts with the magnetic field to produce motion.

• It is usually made up of coils of wire wrapped around a core.

• The armature is connected to a shaft and rotates within the magnetic field.

• In a motor, the armature receives ele...read more

Q3. What is voltage
Ans. 
Voltage is the difference in electric potential between two points in a circuit, measured in volts.
• Voltage is the driving force that pushes electric current through a circuit

• It is measured in volts (V)

• Voltage can be either direct current (DC) or alternating current (AC)

• Higher voltage means more potential energy available to move electrons

• Examples: A battery provides a voltage difference to power a flashlight, a wall ou

Q4. What is current
Ans. 
Current is the flow of electric charge in a circuit.
• Current is measured in Amperes (A)

• It is the rate of flow of electric charge through a conductor

• Current flows from high potential to low potential

• There are two types of current - AC (Alternating Current) and DC (Direct Current)

• Examples of current include the flow of electrons in a wire when a light bulb is turned on

Q2. What is transformer
Ans. 
A transformer is a device that transfers electrical energy between two or more circuits through electromagnetic induction.
• Consists of two or more coils of insulated wire wrapped around a core

• Primary coil receives electrical energy and induces a magnetic field in the core

• Secondary coil receives energy from the magnetic field and transfers it to the load

• Used to step up or step down voltage levels in electrical systems

• Com...read more

Q3. What is capacitor
Ans. 
A capacitor is an electronic component that stores and releases electrical energy in a circuit.
• Capacitors consist of two conductive plates separated by an insulating material called a dielectric.

• They are used to filter out noise in electronic circuits, store energy in flash cameras, and smooth out voltage fluctuations in power supplies.

• Capacitance is measured in Farads (F) and determines how much charge a capacitor can...read more

Q5. What is ac and dc
Ans. 
AC stands for alternating current, which periodically changes direction. DC stands for direct current, which flows in one direction.
• AC is commonly used in household appliances and power distribution systems.

• DC is commonly used in batteries and electronic devices.

• AC changes direction periodically, while DC flows in one direction continuously.

• AC is generated by power stations and transmitted over long distances.

• DC is use...read more

Q1. What is power factor?
Ans. 
Power factor is a measure of how effectively electrical power is being converted into useful work output.
• Power factor is the ratio of real power (kW) to apparent power (kVA) in an electrical system.

• It is a number between 0 and 1, with 1 representing perfect efficiency.

• Low power factor can result in increased energy costs and inefficient use of electrical power.

• Power factor correction can be implemented to improve effic...read more

Q2. Power Factory(cosphi)=Actual power/Apparent power
Ans. 
Power factor is the ratio of actual power to apparent power in an electrical system.
• Power factor is a measure of how effectively electrical power is being used in a system.

• It is calculated by dividing the actual power (in watts) by the apparent power (in volt-amperes).

• A power factor of 1 indicates perfect efficiency, while a lower power factor indicates inefficiency.

• For example, if a system has an actual power of 800W ...read more

Q1. How transformer works.
Ans. 
Transformers work by transferring electrical energy between two or more circuits through electromagnetic induction.
• Transformers have two coils of wire, known as the primary and secondary coils.

• When an alternating current flows through the primary coil, it creates a changing magnetic field.

• This changing magnetic field induces a voltage in the secondary coil, transferring electrical energy between the two circuits.

• Transf...read more
