Q1. What is Transformer
Ans. 
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 ...read more

Q2. What is rectifier
Ans. 
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

Q3. Current of unit .......
Ans. 
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...read more

Q4. Transformers rating in KVA
Ans. 
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

Q5. What is loop law?
Ans. 
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...read more

Q1. What is the Transformer
Ans. 
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
