A transformer is a device that transfers electrical energy between two or more circuits through electromagnetic induction.
Consists of two coils of wire, known as primary and secondary coils
Primary coil receives electrical energy and creates a magnetic field
Magnetic field induces a voltage in the secondary coil, transferring energy
Used in power distribution, voltage regulation, and electrical isolation
I applied via Company Website and was interviewed before Jan 2023. There was 1 interview round.
The question is asking about the current of a unit.
The current of a unit refers to the amount of electric current flowing through a specific unit or device.
It is typically measured in amperes (A) or milliamperes (mA).
The current of a unit can vary depending on the specific device or circuit being discussed.
For example, the current of a unit could refer to the current flowing through a resistor, a transistor, or a motor...
Transformers are rated in KVA (kilovolt-amperes) to indicate their power capacity.
KVA stands for kilovolt-amperes, which is a unit of apparent power.
The KVA rating of a transformer indicates the maximum amount of power it can handle.
Transformers are available in various KVA ratings to suit different power requirements.
Higher KVA ratings indicate higher power capacity.
For example, a transformer with a 100 KVA rating can
Loop law, also known as Kirchhoff's voltage law, states that the sum of the voltages in any closed loop in a circuit is zero.
Loop law is a fundamental principle in electrical engineering.
It is also known as Kirchhoff's voltage law (KVL).
According to loop law, the algebraic sum of the potential differences (voltages) around any closed loop in a circuit is always zero.
It is based on the principle of conservation of energ...
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 the voltage in an electrical circuit.
They consist of two or more coils of wire, known as windings, that are wound around a core made of magnetic material.
The primary winding receives electrical energy from a power source, while the secondary ...
A rectifier is an electrical device that converts alternating current (AC) to direct current (DC).
Rectifiers are commonly used in power supplies to convert AC voltage to DC voltage.
They are made up of diodes, which allow current to flow in only one direction.
Rectifiers can be half-wave or full-wave, depending on the number of diodes used.
Examples of rectifiers include bridge rectifiers, vacuum tube rectifiers, and soli

LOTO stands for Lockout/Tagout, a safety procedure used to ensure that dangerous machines are properly shut off and not started up again prior to the completion of maintenance or servicing work.
LOTO involves locking the energy isolating devices with an assigned individual lock and tag to prevent the machine from being turned on.
Types of LOTO include electrical LOTO, mechanical LOTO, and pneumatic LOTO.
Examples of LOTO ...

Transfer principle involves the movement of energy or information from one system to another.
Transfer principle is based on the concept of transferring energy or information from one source to another.
It is commonly used in electrical engineering to transfer power from a source to a load.
Examples include power transfer in transformers, data transfer in communication systems, and heat transfer in thermal systems.
