I was interviewed in Jan 2025.
Skills and problem-solving.
A comprehensive analysis of a topic.
A standardized assessment.
In a step-down transformer, voltage is reduced by having more turns in the secondary coil than in the primary coil.
Step-down transformers have a higher number of turns in the secondary coil compared to the primary coil.
This results in a decrease in voltage from the primary to the secondary coil.
The ratio of turns in the primary and secondary coils determines the amount of voltage reduction.
For example, a step-down tran...
A transformer is an electrical device that transfers electrical energy between two or more circuits through electromagnetic induction.
Transformers are used to increase or decrease voltage levels in electrical circuits.
They consist of two coils of wire, known as the primary and secondary coils, wrapped around a core made of iron or other magnetic materials.
Transformers are commonly used in power distribution systems to ...
Voltage is the difference in electric potential between two points in a circuit, measured in volts.
Voltage is the force that pushes electric current through a circuit.
It is measured in volts (V).
Higher voltage means more potential energy for electrons to flow.
Voltage can be DC (direct current) or AC (alternating current).
Ohm's Law. state that the strength of the current flowing in close circuit at a constant temp its directly propertional to the voltage across conductors propertional to resistance
Different types of motors include DC motors, AC motors, stepper motors, and servo motors.
DC motors: Direct current motors that convert electrical energy into mechanical energy.
AC motors: Alternating current motors that use alternating current to produce rotational motion.
Stepper motors: Motors that move in discrete steps, commonly used in precision applications.
Servo motors: Motors that use feedback to control position
A generator in electrical engineering is a device that converts mechanical energy into electrical energy.
Generators are commonly used in power plants to generate electricity for homes and businesses.
They can also be used in portable devices like RVs or construction sites.
Generators work by rotating a coil of wire within a magnetic field to create an electric current.
There are different types of generators including die

Java is a high-level programming language used for developing applications and software.
Java is object-oriented and platform-independent.
It is used for developing web, mobile, and desktop applications.
Java code is compiled into bytecode and executed by the Java Virtual Machine (JVM).
Popular frameworks and tools for Java development include Spring, Hibernate, and Maven.
I applied via Naukri.com and was interviewed before Jun 2020. There was 1 interview round.

Swapping two numbers without using a temp variable
Use arithmetic operations to swap the values
Add the two numbers and store the result in the first variable
Subtract the second variable from the result and store it in the second variable
Subtract the second variable from the first variable to get the original value of the second variable
Example: a=5, b=7; a=a+b=12, b=a-b=5, a=a-b=7
I applied via Company Website and was interviewed before Jan 2021. There was 1 interview round.
I applied via Naukri.com and was interviewed in Jun 2021. There were 3 interview rounds.
The current in a transformer is made by inducing voltage across the primary coil.
The primary coil of a transformer is connected to an alternating current (AC) source.
The alternating current in the primary coil creates a changing magnetic field.
This changing magnetic field induces a voltage across the secondary coil.
The induced voltage in the secondary coil causes a current to flow through it.
The current in the secondar...
DC shunt motors are a type of direct current motor that have a parallel field winding and a series armature winding.
DC shunt motors have a parallel field winding and a series armature winding.
They are commonly used in applications that require constant speed and moderate starting torque.
The speed of a DC shunt motor can be controlled by varying the field current or the armature voltage.
DC shunt motors are widely used i...
A DC shunt motor is a type of direct current motor that has a shunt field winding connected in parallel with the armature winding.
The field winding and armature winding are connected in parallel
The shunt motor has a relatively constant speed-torque characteristic
The speed of the motor can be controlled by varying the field current
The motor provides good starting torque
The shunt motor is commonly used in applications wh...
