What is used to apply current to the client's skin in electrotherapy?

  1. An insulator

  2. A transformer

  3. A capacitor

  4. An electrode

The correct answer is: An electrode

An insulator is used to prevent the flow of electric current, so it would not be used to apply current to the client's skin. A transformer is used to change the voltage of an electric current, so it would not be used for direct application to the client's skin. A capacitor is a device used to store electric charge, so it also would not be directly used to apply current to the client's skin. An electrode is the correct answer because it is the part of an electrical device that directly contacts the client's skin and delivers the current.
