Answer: The decomposition of a substance by an electric current is called electrolysis.
Explanation:
Electrolysis is defined as the process in which a chemical substance decomposes when an electric current is passed through it.
Basically, in electrolysis we use electrical energy to carry out a chemical change.
For example, when electric current is passed through water then it breaks down into hydrogen and oxygen.
Thus, we can conclude that decomposition of a substance by an electric current is called electrolysis.
