Physics chemistry maths
Ohm's law states that the current flowing through a conductor is directly proportional to the voltage across it, and inversely proportional to the resistance of the conductor.
Ohm's law is represented by the formula V = I * R, where V is voltage, I is current, and R is resistance.
It helps in calculating the relationship between voltage, current, and resistance in an electrical circuit.
For example, if a circuit has a vol...
A galvanometer is a device used to detect and measure small electric currents.
Galvanometers typically consist of a coil of wire in a magnetic field, which deflects in response to the current flowing through it.
They are often used as components in more complex instruments like ammeters and voltmeters.
Galvanometers can be analog or digital, with analog versions displaying readings on a scale and digital versions showing ...
Power factor is the ratio of real power to apparent power in an electrical system.
Power factor is a measure of how effectively electrical power is being used in a system.
It is calculated by dividing the real power (in watts) by the apparent power (in volt-amperes).
A power factor of 1 indicates all the power is being used effectively, while a power factor less than 1 indicates inefficiency.
Improving power factor can red...
Galvanization is the process of applying a protective zinc coating to steel or iron to prevent rusting.
Galvanization involves immersing the metal in a bath of molten zinc or using an electroplating process.
The zinc coating acts as a sacrificial anode, protecting the underlying metal from corrosion.
Common examples of galvanized items include galvanized steel pipes, fences, and roofing materials.

I applied via Job Portal and was interviewed before May 2023. There were 3 interview rounds.
Light is a form of electromagnetic radiation that is visible to the human eye. It is used for illumination, communication, and various other applications.
Light is a type of electromagnetic radiation that is visible to the human eye.
It can be produced naturally (sunlight) or artificially (light bulbs, LEDs).
Light is used for illumination in homes, offices, streets, etc.
It is also used for communication (fiber optics), p...
A transformer is a device that transfers electrical energy from one circuit to another through electromagnetic induction.
Transformers consist of two coils of wire, known as the primary and secondary coils.
The primary coil is connected to a power source, creating a magnetic field when current flows through it.
This magnetic field induces a voltage in the secondary coil, allowing for the transfer of electrical energy.
Tran...
A cooling tower is a specialized heat exchanger in which air and water are brought into direct contact to reduce the water's temperature.
Used in HVAC systems to remove heat from a building or industrial process
Water is circulated through the tower and exposed to air, causing evaporation and cooling
Commonly seen in power plants, refineries, and large buildings
Current is the flow of electric charge in a circuit.
Current is measured in Amperes (A).
It is the rate of flow of electric charge past a point in a circuit.
There are two types of current - direct current (DC) and alternating current (AC).
Current is calculated using Ohm's Law: I = V/R, where I is current, V is voltage, and R is resistance.
A breaker is an electrical switch designed to protect an electrical circuit from damage caused by overload or short circuit.
A breaker automatically interrupts the flow of electricity when it detects an overload or short circuit.
Breakers come in different types such as circuit breakers, fuse boxes, and ground fault circuit interrupters (GFCIs).
They are essential for preventing electrical fires and protecting electrical ...
CRM stands for Customer Relationship Management. It is a strategy used by companies to manage interactions with customers and potential customers.
CRM involves using technology to organize, automate, and synchronize sales, marketing, customer service, and technical support.
It helps companies build and maintain relationships with customers, streamline processes, and improve profitability.
Examples of CRM software include
A megger is a portable instrument used to measure the insulation resistance of electrical equipment.
Measures insulation resistance to detect any faults or breakdowns in electrical insulation
Helps prevent electrical accidents and equipment failures
Commonly used in maintenance and troubleshooting of electrical systems
MW stands for megawatt, a unit of power equal to one million watts.
MW is a unit of power used to measure the rate at which energy is generated or consumed.
1 MW is equal to 1 million watts or 1,000 kilowatts.
It is commonly used in the context of electricity generation and consumption.
For example, a large wind turbine may have a capacity of 2 MW, meaning it can generate 2 million watts of power.

To check a motor in megar, use a megohmmeter to measure the insulation resistance.
Disconnect the motor from the power source.
Remove the motor leads from the ground.
Connect the megohmmeter to the motor leads and ground.
Measure the insulation resistance.
Compare the reading to the manufacturer's specifications.
An ignitor is used in sodium lamps to start and maintain the discharge of sodium vapor.
Sodium lamps require a high voltage to start the discharge of sodium vapor.
The ignitor provides a high voltage pulse to start the discharge.
Once the discharge is started, the ignitor is no longer needed.
The ignitor also helps to maintain the discharge by providing a small current to keep the lamp lit.
Without an ignitor, the lamp woul...
