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

A resistor is an electronic component that resists the flow of electric current.
Resistors are used to control the amount of current flowing in a circuit.
They are typically made of a material that has high resistance to the flow of electricity.
The resistance of a resistor is measured in ohms (Ω).
Resistors come in different shapes and sizes, and are color-coded to indicate their resistance value.
Examples of applications ...
A pnp junction is a type of bipolar junction transistor (BJT) that consists of a p-doped semiconductor sandwiched between two n-doped semiconductors.
The pnp junction is a three-layer device with a p-type layer sandwiched between two n-type layers.
It is commonly used in amplification and switching circuits.
In a pnp transistor, the majority charge carriers are holes, which flow from the emitter to the collector.
The pnp j...
