An altering and interrupted current that proceeds a mechanical reaction with no chemical effect is the _____________.

  1. Direct Current

  2. Galvanic Current

  3. Faradic Current

  4. Tesla Current

The correct answer is: Faradic Current

The incorrect options A) Direct Current, or DC, is a unidirectional flow of electrical charge. It does not meet the criteria of a current that proceeds mechanical reaction. B) Galvanic Current is also known as DC. Thus, it also cannot be the answer to this question. D) Tesla Current, or AC, is a type of current that continuously changes direction and is typically used to power homes and electronics. It does not fit the description of a current that proceeds a mechanical reaction without any chemical effect. Overall, the key to this question is understanding the definition of the term "current." A current is the flow of electrical charge, and in this case, only the Faradic Current, or interrupted DC, meets the criteria of being able to trigger a mechanical reaction without any chemical effect.
