Q1. What is hunting in synchronous motor , principle of synchronous motor, types of transformer
Ans. 
Hunting in synchronous motor refers to small oscillations in speed, principle involves magnetic field interaction, types of transformers include step-up and step-down.
• Hunting in synchronous motor occurs when the rotor oscillates around the synchronous speed due to sudden load changes.

• Principle of synchronous motor involves the interaction of magnetic fields between the stator and rotor to maintain synchronous speed.

Q2. What is a construction of transformer, different types of dc motor
Ans. 
A transformer is a device that transfers electrical energy between two or more circuits through electromagnetic induction. Different types of DC motors include brushed, brushless, and stepper motors.
• Transformers consist of primary and secondary coils wrapped around a core, used to step up or step down voltage levels.

• DC motors include brushed motors, which use brushes to conduct current, brushless motors which use elect...read more

Q3. Working of induction motor , types of starter in induction motor
Ans. 
Induction motors work on the principle of electromagnetic induction. Types of starters include DOL, star-delta, and soft starters.
• Induction motors operate based on the principle of electromagnetic induction, where a rotating magnetic field is produced by the stator winding.

• Types of starters for induction motors include Direct Online (DOL) starters, which provide full voltage to the motor at start-up.

• Star-delta starters...read more

Q1. What is GD&T and their use?
Ans. 
GD&T stands for Geometric Dimensioning and Tolerancing. It is a system for defining and communicating engineering tolerances.
• GD&T is used to specify the allowable variations in form, size, and orientation of part features.

• It helps ensure that parts fit together properly and function as intended.

• GD&T uses symbols, such as concentricity, flatness, and perpendicularity, to communicate tolerances.

• It is commonly used in eng...read more

Q1. What is ohms low
Ans. 
Ohm's Law states that the current flowing through a conductor between two points is directly proportional to the voltage across the two points.
• Ohm's Law is represented by the equation V = IR, where V is voltage, I is current, and R is resistance.

• It is named after German physicist Georg Simon Ohm, who first formulated the law in 1827.

• Ohm's Law is fundamental in the field of electrical engineering and is used to analyze

Q2. 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 voltage levels in electrical circuits.

• They consist of two coils of wire, known as the primary and secondary coils, wrapped around a core.

• Step-up transformers increase voltage levels, while step-down transformers decrease voltage levels.

• Transf...read more
