Citelum India Electrical Technician Interview Questions, Process, and Tips

An electrician is a skilled tradesperson who installs, maintains, and repairs electrical systems and equipment.

• Electricians work with a variety of tools and equipment to install and repair electrical systems in buildings, homes, and other structures.

• They are responsible for reading and interpreting electrical blueprints and diagrams to determine the layout and installation of wiring, circuits, and other electrical comp...read more

Electricity is the flow of electric charge through a conductor.

• Electricity is a form of energy resulting from the movement of charged particles.

• It is commonly generated by power plants and used for various purposes such as lighting, heating, and powering electronic devices.

• Electricity can be categorized into two types: direct current (DC) and alternating current (AC).

• DC flows in one direction, while AC alternates its d...read more

Electricity can be generated through various methods such as chemical reactions, electromagnetic induction, and photovoltaic effect.

• Chemical reactions, such as in batteries, can produce electricity.

• Electromagnetic induction, as in generators, converts mechanical energy into electrical energy.

• The photovoltaic effect in solar panels converts sunlight directly into electricity.

Transformer works on the principle of electromagnetic induction.

• Transformers operate based on the relationship between magnetic fields and electric currents.

• They use two coils, primary and secondary, to transfer electrical energy from one circuit to another.

• The primary coil is connected to an alternating current (AC) source, creating a changing magnetic field.

• This changing magnetic field induces a voltage in the second...read more

The number of transformers depends on the specific context and location.

• The number of transformers can vary depending on the size and purpose of the electrical system.

• In a residential area, there may be one transformer serving multiple houses.

• In a commercial or industrial setting, there may be multiple transformers to meet the power demands.

• Transformers can also be found in power substations, where they step up or step...read more
