What is the definition of electricity?

1. A form of energy resulting from charged particles

2. A material that can conduct light

3. A measure of thermal energy

4. A type of mechanical force

The correct answer is: A form of energy resulting from charged particles

Electricity is defined as a form of energy that is produced by the movement of charged particles, typically electrons. This definition captures the essence of electricity as it encompasses both the energy itself and its origins related to charged entities. In various applications, electricity can manifest in numerous forms such as static electricity, current electricity, and electromagnetic fields, always fundamentally linked to the dynamics of these charged particles. The other choices do not fit this definition. For instance, a material that can conduct light pertains to optical properties rather than electrical ones. A measure of thermal energy relates to temperature and heat, and does not describe electricity. Similarly, a type of mechanical force does not encompass the characteristics or behavior of electricity. Understanding electricity as energy derived from charged particles is crucial for grasping its nature and applications in technology and physics.
