Electrical Fundamentals Quiz

An induction motor works on the principle of electromagnetic induction, where a rotating magnetic field in the stator induces current in the rotor, causing it to rotate. It is commonly used in various industrial and commercial applications, such as pumps, compressors, and conveyor systems. The advantages of induction motors include their simplicity, robustness, and low maintenance requirements.

Parallel connection in electrical circuits is used to connect multiple devices or components across the same voltage supply. The advantages of parallel connection include the ability to independently control each component, and if one component fails, it does not affect the others. However, the main disadvantage is that it requires more wiring and can lead to unequal current distribution among the components.

The resistor color coding chart is used to identify the resistance value and tolerance of a resistor. It is crucial in electrical engineering as it allows for easy identification and selection of resistors for specific circuit requirements. The color coding provides a quick visual reference, enabling engineers and technicians to accurately interpret and use resistors in various electronic applications.
