How this entity was disambiguated
This entity first appeared as the object of triple T22067513 — resolving that mention is where its identity was fixed. The disambiguator weighed these candidate entities and picked the highlighted one (or “None”, minting a new entity). This is how homonymy is resolved: the same surface form can point to different entities.

Target entity: Hofmann voltameter Context triple: [August Wilhelm von Hofmann, knownFor, Hofmann voltameter]
-
A.
Bunsen cell
The Bunsen cell is a 19th-century zinc–carbon electrochemical cell that provided a relatively powerful and inexpensive source of direct current for early laboratory and industrial applications.
-
B.
Voltaic pile
The Voltaic pile is the first chemical battery, invented by Alessandro Volta, which provided a continuous and reliable source of electric current and laid the foundation for modern electrochemistry and electrical engineering.
-
C.
Nernst–Lamp
The Nernst–Lamp is an early type of electric lamp that used a heated ceramic rod as a light-emitting element and played a significant role in the development of incandescent lighting technology.
-
D.
Leyden jar
The Leyden jar is an early form of capacitor that stores static electric charge on metal foil layers separated by an insulating glass container.
-
E.
Bridgman anvil cell
The Bridgman anvil cell is a high-pressure device that uses opposed anvils to compress small samples to extreme pressures for experimental research in physics and materials science.
- F. None of above. chosen
- G. Unsure - the case is ambiguous/there is not enough information to decide.
