How does a Capacitor protect against voltage spikes?
When a voltage is applied to the capacitor, the electrons from one plate are attracted to the other plate, creating an electric field between them. The capacitor can then release this stored energy when needed. 4. Can a capacitor protect against all voltage spikes? No, a capacitor has a limited capacity to absorb voltage spikes.
