Alpha Teknisk Interview Questions, Process, and Tips

A relay is an electrically operated switch that uses an electromagnet to mechanically open or close a circuit.

• Relays are used to control high voltage or high current circuits with low voltage or low current signals.

• When a current flows through the coil of the relay, it creates a magnetic field that attracts a metal armature, which closes the circuit.

• Relays are commonly used in automotive, industrial, and household appl...read more

Self starter motor is responsible for starting the engine without the need for external power source.

• Self starter motor is an electric motor that is used to start an engine without the need for external power source.

• It is commonly used in automobiles, motorcycles, and other machines that require internal combustion engines.

• The self starter motor is activated by turning the ignition key, which sends an electrical signal...read more

The basic function of an engine is to convert fuel into mechanical energy through a series of cycles.

• An engine takes in air and fuel, compresses it, ignites the mixture, and then expels the exhaust gases.

• The four-stroke cycle includes intake, compression, power, and exhaust strokes.

• The two-stroke cycle combines intake and compression into one stroke, and power and exhaust into another.

• Examples of engines include gasoli

Hydraulics is a branch of science and engineering that deals with the mechanical properties of liquids, especially water or oil, and their applications in engineering.

• Hydraulics involves the study of fluid mechanics and the behavior of liquids under pressure.

• It is used in various applications such as hydraulic machinery, hydraulic brakes in vehicles, and hydraulic lifts.

• Hydraulic systems work based on Pascal's law, whi...read more
