Bses Rajdhani Power Interview Questions, Process, and Tips

Electricity is the flow of electric charge through a conductor.

• Electricity is a form of energy resulting from the existence of charged particles (such as electrons or protons).

• It can be generated by various means such as chemical reactions, electromagnetic induction, or solar panels.

• Electricity can be harnessed to power various devices and systems, from light bulbs to computers.

• It is essential for modern society, enabl...read more

Voltage is the difference in electric potential between two points in a circuit, measured in volts.

• Voltage is the driving force that pushes electric current through a circuit

• It is measured in volts (V)

• Voltage can be positive or negative, depending on the direction of current flow

• Higher voltage means more potential energy available to move electrons

• Examples: A battery provides voltage to power a flashlight, a wall outle

A circuit is a closed loop through which an electric current can flow.

• A circuit consists of components such as resistors, capacitors, inductors, and power sources.

• There are two types of circuits: series circuits (components connected in a single path) and parallel circuits (components connected in multiple paths).

• Circuits can be used to perform various functions such as amplification, filtering, and signal processing.

• E...read more

Current is the flow of electric charge, while voltage is the force that drives the current.

• Current is the rate of flow of electric charge through a conductor.

• Voltage is the difference in electric potential between two points in a circuit.

• Current is measured in Amperes (A), while voltage is measured in Volts (V).

• Ohm's Law relates current, voltage, and resistance in a circuit: V = I * R.

• In a simple analogy, current is li...read more

Earthing is used in electrical systems to protect against electric shock and ensure proper functioning of equipment.

• Earthing is used to provide a path for fault currents to flow safely to the ground.

• It helps to stabilize voltage levels and prevent damage to equipment.

• Different types of earthing systems include TN, TT, and IT systems.

• Examples of earthing methods include rod earthing, plate earthing, and pipe earthing.

Yes, SCADA stands for Supervisory Control and Data Acquisition. It is a system used for monitoring and controlling industrial processes.

• SCADA systems are used in various industries such as power plants, water treatment facilities, and manufacturing plants.

• They allow operators to remotely monitor and control processes in real-time.

• SCADA systems typically consist of sensors, controllers, and a human-machine interface (HM...read more

Types of losses in power distribution include resistance losses, core losses, and dielectric losses.

• Resistance losses occur due to the resistance of the conductors, leading to heat dissipation.

• Core losses occur in transformers due to hysteresis and eddy current losses.

• Dielectric losses occur in insulating materials due to polarization and leakage currents.

Power distribution system is a network of electrical components used to deliver electricity from the generation source to the end users.

• Power generation at a central location

• Transmission of electricity through high voltage lines

• Distribution through substations and transformers

• Delivery to end users via distribution lines

• Utilization by consumers for various applications

Transformers are electrical devices that transfer electrical energy between two or more circuits through electromagnetic induction.

• Transformers can be classified based on their construction (core type, shell type), cooling method (oil-immersed, dry-type), and application (power, distribution, instrument, etc.)

• Examples of transformers include power transformers used in electrical substations, distribution transformers o...read more

There are three main types of circuit breakers: thermal, magnetic, and thermal-magnetic.

• Thermal circuit breakers use a bimetallic strip to break the circuit when it overheats.

• Magnetic circuit breakers use a solenoid to trip the circuit when it detects a sudden surge of current.

• Thermal-magnetic circuit breakers combine the features of both thermal and magnetic circuit breakers for better protection.

• Examples include Squa

Meter is a unit of length in the metric system, equal to 100 centimeters or approximately 39.37 inches.

• Meter is the base unit of length in the metric system.

• It is equal to 100 centimeters or approximately 39.37 inches.

• Commonly used for measuring distances, heights, and lengths.

• Examples: A standard ruler is typically marked in centimeters and meters.

• Example: The height of a person can be measured in meters.
