A Capacitor in an alternator serves as a vital component for voltage regulation. It acts as an electrical energy storage device, absorbing excess energy during high-demand periods and releasing it during low-demand periods. This functionality helps stabilize the alternator's output voltage, ensuring a consistent and reliable power supply to connected electrical systems and devices. By smoothing out fluctuations in current, the capacitor protects sensitive equipment from voltage spikes and helps maintain optimal performance.

Attributes:
• Helps regulate and stabilize the alternator's output voltage.
• Absorbs excess energy during high-demand periods and releases it during low-demand periods.
• Smooth out fluctuations in current to provide a consistent and reliable power supply.
• Helps protect sensitive electrical devices from voltage spikes and fluctuations.

Application:
A Capacitor in an alternator is to regulate voltage by storing and releasing electrical energy as needed. It helps stabilize the alternator's output voltage, ensuring a consistent and reliable power supply to electrical systems and devices.
