Q1. What is transformer and transformer effect
Ans. 
A transformer is an electrical device that transfers electrical energy from one circuit to another through electromagnetic induction.
• Transformers are used to increase or decrease the voltage of an alternating current (AC) power supply.

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

• When an AC voltage is applied to the primary coil, it creates a magnetic field th...read more

Q2. What is indicator and advantages
Ans. 
An indicator is a device that shows the status or level of something. It has advantages like easy monitoring and quick identification of problems.
• Indicators provide real-time information about the status or level of a process or system.

• They help in monitoring and controlling the process or system.

• Indicators can quickly identify problems or deviations from the desired level.

• They are easy to use and require minimal train...read more

Q3. What is motor and working
Ans. 
A motor is a device that converts electrical energy into mechanical energy to produce motion.
• Motors are used in various applications such as electric vehicles, industrial machinery, and household appliances.

• They work on the principle of electromagnetic induction or the interaction between magnetic fields and electric currents.

• The basic components of a motor include a rotor, stator, and commutator or brushes.

• There are d...read more

Q4. What is synchronous motor
Ans. 
A synchronous motor is an AC motor that operates at a constant speed determined by the frequency of the power supply.
• Synchronous motors have a rotor that rotates at the same speed as the rotating magnetic field in the stator.

• They are commonly used in applications that require constant speed, such as industrial machinery and power generation.

• Synchronous motors are more efficient than induction motors at full load.

• They a...read more

Q5. What is induction motor
Ans. 
An induction motor is an AC electric motor in which the electric current in the rotor is produced by electromagnetic induction from the magnetic field of the stator winding.
• Induction motors are widely used in industrial applications due to their simplicity, reliability, and low cost.

• They are commonly used in fans, pumps, compressors, and other machinery.

• Induction motors work by inducing a magnetic field in the rotor, w...read more
