Forbes & Company Diploma Trainee Engineer Interview Questions and Answers

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 is connected to the power source, while the secondary winding is con...read more

A motor is a device that converts electrical energy into mechanical energy based on the principles of electromagnetism.

• A motor consists of a rotor and a stator.

• When an electric current flows through the stator windings, it creates a magnetic field.

• The interaction between the magnetic field and the rotor's magnetic field causes the rotor to rotate.

• Motors can be classified into various types such as DC motors, AC motors,...read more
