Ballast

Ballast is material placed in the lower part of a vessel, structure, or system to provide stability and balance. In ships, ballast—often water, dirt, or heavy stones—keeps the vessel steady and prevents excessive tilting when cargo is loaded or unloaded. In technology and lighting, ballast regulates the electrical current to bulbs, ensuring they operate safely and efficiently. Overall, ballast functions as a stabilizing force, maintaining equilibrium whether in maritime, electrical, or engineering contexts.
