3. Capacity of undergoing or suffering; fitness to be acted upon; susceptibility; -- called also passive power; as, great power of endurance. Power, then, is active and passive; faculty is active power or capacity; capacity is passive power. Sir W. Hamilton.

Note: Power is used adjectively, denoting, driven, or adapted to be driven, by machinery, and not actuated directly by the hand or foot; as, a power lathe; a power loom; a power press.
