DET Supervisor Interview Questions and Answers

A cylinder is cylindrical because it has a curved surface and two parallel circular bases.

• A cylinder is a three-dimensional shape with a curved surface and two parallel circular bases.

• The curved surface of a cylinder is formed by connecting the points on the circumference of the bases.

• The two bases of a cylinder are congruent and parallel to each other.

• Examples of cylinders include a soda can, a pencil, and a roll of paper towels.

I use oil paint because of its versatility and ability to create rich, vibrant colors.

• Oil paint has a slow drying time, allowing for blending and layering of colors

• It can be thinned with solvents or thickened with mediums for different effects

• Oil paint also has a long lifespan and can resist cracking over time

• Examples of famous oil painters include Vincent van Gogh, Rembrandt, and Leonardo da Vinci

An induction motor is a type of AC motor where power is supplied to the rotor by electromagnetic induction.

• Induction motors are commonly used in various applications such as industrial machinery, pumps, fans, and compressors.

• They do not require brushes to transfer power to the rotor, making them more reliable and low maintenance.

• The speed of an induction motor is determined by the frequency of the AC power supply and the number of poles in the motor.

• They are efficient and cos...read more

Oil paint is used as a lubricant for engines.

• Oil paint helps reduce friction between engine parts

• It also helps cool the engine by absorbing heat

• Regular oil changes are necessary to maintain engine health

A two-stroke engine is a type of internal combustion engine that completes a power cycle in two strokes of the piston.

• It is commonly used in small engines such as motorcycles, chainsaws, and outboard motors.

• It combines the intake, compression, combustion, and exhaust processes into two strokes of the piston.

• It requires a mixture of fuel and oil for lubrication and cooling.

• It is less fuel-efficient and produces more pollution compared to a four-stroke engine.

• Examples of two-st...read more

FIFO and LIFO are inventory management methods. FIFO stands for First-In, First-Out and LIFO stands for Last-In, First-Out.

• FIFO assumes that the first items added to inventory are the first sold or used.

• LIFO assumes that the last items added to inventory are the first sold or used.

• FIFO is commonly used in industries with perishable goods, such as food and beverage.

• LIFO is commonly used in industries with non-perishable goods, such as electronics and hardware.

• FIFO results in l...read more

The protection of a transformer involves measures to prevent damage from overcurrent, overvoltage, overheating, and short circuits.

• Use fuses or circuit breakers to protect against overcurrent

• Install surge arresters to protect against overvoltage

• Use temperature sensors and cooling systems to prevent overheating

• Implement differential relays to detect and isolate short circuits

• Regular maintenance and testing to ensure proper functioning

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 = IR, 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 voltage of 12 volts and a resistance of 4 ohms, the current flow...read more
