Final answer:
The process known as electrotherapy involves using an electric current in a water-based solution to achieve therapeutic effects. Electrolysis is different and pertains to the use of electricity to drive chemical reactions and isolate metals.
Step-by-step explanation:
The effect that is created when an electric current travels through a water-based solution to produce relaxing or stimulating results is known as electrotherapy. Electrolysis, on the other hand, is a different process where direct current electricity passes through a water solution containing an electrolyte like H₂SO₄, resulting in the formation of hydrogen at the cathode and oxygen at the anode.
It is important to note that electrolysis involves electrical energy driving unfavorable chemical reactions to completion and is used in the isolation of reactive metals in their pure forms, such as sodium, aluminum, and magnesium.
Electrolytes are substances that produce electrically conducting solutions when dissolved in water or another polar solvent. The concentration of dissolved ions can be assessed by measuring the electrical current flow in a solution, which informs us about the solution's conductive properties.
