Q1. What is an ideal transformer
Ans. 
An ideal transformer is a theoretical transformer with no losses and perfect efficiency.
• An ideal transformer has no resistance, leakage inductance, or core losses.

• It has a turns ratio that perfectly converts voltage and current from primary to secondary windings.

• Efficiency is 100% in an ideal transformer.

• Real transformers have losses due to resistance, eddy currents, and hysteresis.

Q2. Relation between kva and kw
Ans. 
kVA is the apparent power, while kW is the real power. The relationship between them is determined by the power factor.
• kVA is the product of voltage and current in a circuit, while kW is the actual power consumed by the load.

• The relationship between kVA and kW is determined by the power factor of the load.

• Power factor = kW / kVA. A power factor of 1 indicates all power is being used efficiently.

• For example, if a load h...read more

Q1. Who is the home s law
Ans. 
Home's law is a principle that states that the current flowing through a conductor is directly proportional to the voltage applied across it.
• Home's law is also known as Ohm's law.

• It is expressed as I = V/R, where I is the current, V is the voltage, and R is the resistance.

• This law is fundamental to the study of electrical circuits and is used to calculate the behavior of circuits.

• For example, if the voltage across a re...read more

Q2. What is current unit?
Ans. 
The current unit is the ampere (A), which measures the flow of electric charge.
• The unit of electric current is the ampere (A).

• Current is the rate of flow of electric charge.

• It is measured using an ammeter.

• One ampere is equal to one coulomb of charge passing through a point in one second.

Q1. What is ohm law and current symble
Ans. 
Ohm's law states that the current flowing through a conductor is directly proportional to the voltage applied across it.
• Ohm's law is expressed as V = I * R, where V is the voltage, I is the current, and R is the resistance.

• The current symbol is represented by the letter 'I'.

• Ohm's law is fundamental in understanding and analyzing electrical circuits.

• Example: If a circuit has a voltage of 12 volts and a resistance of 4 o...read more

Q1. Tow type of winding ?
Ans. 
The two types of winding in electrical engineering are lap winding and wave winding.
• Lap winding is used in DC machines and is characterized by multiple parallel paths for current flow.

• Wave winding is used in AC machines and is characterized by a single path for current flow.

• Lap winding provides high current capacity and low voltage output, while wave winding provides low current capacity and high voltage output.

• In lap ...read more

Q2. What is men by primary winding
Ans. 
The primary winding is the first coil in a transformer that receives electrical energy.
• The primary winding is typically connected to the power source.

• It is responsible for receiving and transmitting electrical energy to the secondary winding.

• The number of turns in the primary winding determines the voltage ratio between the primary and secondary sides.

• Primary windings are commonly found in transformers, induction motor
