Q1. What is motor?and explain working of motor
Ans. 
A motor is a device that converts electrical energy into mechanical energy to produce motion.
• Motors can be classified into different types such as DC motors, AC motors, and stepper motors.

• The basic working principle of a motor involves the interaction of magnetic fields to generate force and motion.

• In a DC motor, current flows through a coil within a magnetic field, creating a force that rotates the motor shaft.

• In an A...read more

Q2. Define transformer? Explain types of transformer?
Ans. 
A transformer is a 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.

• There are two main types of transformers: step-up transformers and step-down transformers.

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

• Other types of transformers...read more

Q7. Explain how many types of fault?
Ans. 
There are three main types of faults: normal faults, reverse faults, and strike-slip faults.
• Normal faults occur when the hanging wall drops down relative to the footwall. Example: Basin and Range Province in the western United States.

• Reverse faults occur when the hanging wall moves up relative to the footwall. Example: Rocky Mountains in North America.

• Strike-slip faults occur when the blocks slide past each other horiz...read more

Q2. How does a transformer works. Detailed working and parameters to monitor
Ans. 
A transformer works by transferring electrical energy between two or more circuits through electromagnetic induction.
• Transformers consist of two coils of wire, known as the primary and secondary coils, wrapped around a core made of iron or other magnetic materials.

• When an alternating current flows through the primary coil, it creates a changing magnetic field which induces a voltage in the secondary coil.

• The ratio of t...read more
