CompTIA Network+ Practice Test

Why is it important to know how to discharge capacitors?

1. To enhance the lifespan of devices

2. To prevent potential electric shock

3. To facilitate better energy consumption

4. To increase operational efficiency

The correct answer is: To prevent potential electric shock

Knowing how to discharge capacitors is crucial primarily to prevent potential electric shock. Capacitors can store a significant amount of electrical energy, even when the power source has been removed. This stored energy can be dangerous and pose serious risks to individuals working on or around electronic devices and circuits. When working with electronics such as power supplies, audio amplifiers, or any device that uses capacitors, failing to properly discharge the capacitors can lead to an unexpected release of energy. This release can result in electrical shocks that can be painful, or even life-threatening, depending on the voltage and charge stored in the capacitor. Thus, understanding and practicing the safe method for discharging capacitors is vital for personal safety and the safety of others. Other choices, while relevant to different aspects of electronics and device management, do not directly address the immediate safety concern associated with handling charged capacitors. Enhancing lifespan, better energy consumption, and increasing operational efficiency can be secondary considerations in the context of capacitor handling, but they do not highlight the critical safety implications of discharging capacitors.
