NEIEP Mechanics Practice Exam

Question: 1 / 475

What is crucial about the voltage in polarized electrolytic capacitors?

Current must be equal in both directions

Voltage polarity must be correct

In polarized electrolytic capacitors, it is essential that the voltage polarity must be correct because these components are designed to operate with a specific positive and negative lead. If the voltage is applied in reverse polarity, it can lead to the breakdown of the dielectric layer, potentially causing the capacitor to fail, short-circuit, or even explode. This characteristic is a critical aspect of how these capacitors are constructed and utilized in various circuits.

The correct application of voltage ensures that the capacitor functions as intended, allowing it to store and release electrical energy efficiently. Understanding this crucial feature is fundamental for anyone working with electronics that incorporate such components.
