Sri Gopikrishna Infrastructure Interview Questions, Process, and Tips

Calculate the volume of concrete in a pile with a height of 12 meters and a diameter of 350 mm.

• Calculate the radius of the pile by dividing the diameter by 2 (175 mm)

• Calculate the volume of the pile using the formula V = πr^2h

• Convert the diameter and height to meters for consistent units

• Substitute the values into the formula to find the volume of concrete in the pile

Perlin noise is a type of gradient noise used in computer graphics for creating natural-looking textures and animations.

• Perlin noise is a type of coherent noise, meaning it smoothly transitions from one value to another without sudden jumps.

• It is commonly used in procedural generation for creating realistic terrain, clouds, and other natural phenomena.

• There are different variations of Perlin noise, such as simplex nois...read more

Corona effect is the phenomenon of ionization and luminous discharge around a conductor carrying high voltage in air.

• Occurs when the electric field strength around a conductor exceeds the breakdown strength of air

• Results in ionization of air molecules and formation of a luminous discharge or corona

• Can cause power loss, radio interference, and damage to equipment

• Examples include the hissing sound from high voltage power

Generation is the process of producing electricity, transmission is the movement of electricity over long distances, and distribution is the delivery of electricity to consumers.

• Generation involves converting energy sources such as coal, natural gas, or wind into electricity.

• Transmission involves high voltage power lines that transport electricity over long distances from power plants to substations.

• Distribution involv...read more

The primary side of a transformer can be found by checking the voltage rating on the nameplate.

• Check the nameplate for voltage rating

• The higher voltage rating is usually the primary side

• Use a multimeter to confirm the primary side
