Foseco Interview Questions and Answers

Questions related to electrical engineering concepts such as transformers, AC and DC, motor, electromagnetic induction law, and Ohm's law.

• Transformers are devices that transfer electrical energy from one circuit to another through electromagnetic induction.

• AC (alternating current) changes direction periodically while DC (direct current) flows in one direction only.

• A motor is a device that converts electrical energy into mechanical energy.

• Electromagnetic induction law states t...read more

Questions related to generators, power transmission, and thermocouples.

• Types of generators include diesel, gas, wind, and hydroelectric.

• India's generation capacity is around 370 GW.

• Maximum power transmission in India is around 1,050 GW.

• Transmission of maximum power is important to ensure efficient and reliable power supply.

• A thermocouple is a device used to measure temperature and is commonly used in industrial applications.

Wind power generation converts wind energy into electricity using turbines, harnessing natural wind flow for sustainable energy.

• Wind turbines capture kinetic energy from wind.

• The rotor blades spin, turning a shaft connected to a generator.

• The generator converts mechanical energy into electrical energy.

• Electricity is transmitted through power lines to homes and businesses.

• Example: Offshore wind farms utilize strong sea winds for higher efficiency.

The supply process in a grid system involves generation, transmission, distribution, and consumption of electrical energy.

• 1. Generation: Electricity is generated at power plants using various sources like coal, natural gas, nuclear, or renewables (e.g., solar, wind).

• 2. Transmission: High-voltage transmission lines carry electricity over long distances to minimize energy loss.

• 3. Substations: Voltage is reduced at substations for safe distribution to consumers.

• 4. Distribution: ...read more

Ohm's law states that the current through a conductor between two points is directly proportional to the voltage across the two points.

• Ohm's law is represented by the equation V = IR, where V is voltage, I is current, and R is resistance.

• The power formula is P = VI, where P is power, V is voltage, and I is current.

• Ohm's law is used to calculate the resistance of a circuit and to determine the amount of current flowing through it.

• The power formula is used to calculate the amou...read more
