Automobile Auto Electrician Heavy Interview Questions and Answers

Thick wire is used for self starter to handle high current flow and prevent overheating.

• Thick wire has lower resistance, allowing more current to flow without overheating.

• Self starters require high current to start the engine, which can cause thin wires to overheat and fail.

• Thick wire also ensures efficient power transfer from the battery to the starter motor.

• Examples of thick wires used for self starters include battery cables and starter motor cables.

A fuse is a protective device used in electrical circuits to prevent damage from excessive current flow.

• A fuse is a small, thin wire or strip of metal that melts when excessive current flows through it.

• It is designed to break the circuit and prevent damage to the electrical components.

• Fuses are used to protect electrical devices and wiring from overheating and potential fires.

• They are commonly used in automobiles to protect various electrical systems, such as the lights, radi...read more

There are two types of DC generators: separately excited and self-excited.

• Separately excited DC generators have a separate source of field excitation.

• Self-excited DC generators have their field winding connected to the output of the generator.

• Self-excited DC generators can be further classified into shunt, series, and compound generators.

Electric current is the flow of electric charge through a conductor.

• Electric current is the movement of electrons or charged particles.

• It is measured in amperes (A) and is represented by the symbol 'I'.

• Current flows from a higher potential to a lower potential.

• Direct current (DC) flows in one direction, while alternating current (AC) changes direction periodically.

• Examples of electric current include the flow of electricity in a circuit or the movement of electrons in a wire.
