Question

Why are capacitors rated at higher voltages than the unit line voltage?

A. To increase energy storage.
B. To withstand voltage spikes.
C. To improve efficiency.
D. To reduce power consumption.

Answer 1

Capacitors are rated at higher voltages than the unit line voltage for three main reasons: to increase energy storage, to withstand voltage spikes, and to improve efficiency.

Step-by-step explanation:

Capacitors are rated at higher voltages than the unit line voltage for three main reasons: to increase energy storage, to withstand voltage spikes, and to improve efficiency.

Capacitors are rated at higher voltages than the unit line voltage for several reasons:

1. To increase energy storage: The greater the voltage applied to a capacitor, the greater the charge stored in it. By rating capacitors at higher voltages, they can store more energy.
2. To withstand voltage spikes: Capacitors need to be able to handle sudden voltage spikes without breaking down. Rating them at higher voltages ensures they can withstand these fluctuations.
3. To improve efficiency: Higher voltage ratings allow capacitors to work more efficiently and effectively in electrical systems.
