Question

sara read in a book that in 1800, the italian physicist alessandro volta observed that two metals connected by a conducting liquid produced a continuous transfer of electrons. this phenomenon was different from the rapid static discharge observed by benjamin franklin. saras book was describing voltas observation of: resistance. static electricity. electric current. superconductivity

Explanation:

The book describes a continuous transfer of electrons, which is the definition of electric current. Resistance is opposition to electron flow, static electricity is rapid discharge (different from Volta’s observation), and superconductivity is zero resistance (not mentioned here).

Answer:

electric current.
