Electricity is classified as a form of what?

1. Material

2. Energy

3. Force

4. Movement

The correct answer is: Energy

Electricity is classified as a form of energy because it involves the movement of charged particles, typically electrons, that create an electric current or potential difference. This energy can be harnessed to perform work such as powering devices, heating, or lighting. Understanding electricity in terms of energy is crucial for estheticians, as various treatments and tools that utilize electricity—including galvanic, high-frequency, and LED therapies—rely on this fundamental concept. Recognizing electricity as energy helps estheticians appreciate how these tools function and how they can be effectively applied to enhance treatment outcomes for skin care.
