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:

Electric current is the continuous flow of electrons. Volta's observation of a continuous transfer of electrons between two metals connected by a conducting liquid describes electric current. Resistance is opposition to current flow, static electricity is stationary charge, and superconductivity is zero - resistance flow at low temperatures, which are not what is described here.

Answer:

electric current.
