"Accumulation of electricity" is a technical term used to describe the buildup of electrical charge in a system. This term can also be referred to as "static electricity," "charge accumulation," or "electrostatic buildup." Another synonym for the term is "electric potential," which is the electrical potential energy of a system per unit of charge. Additionally, the term "electric charge" can be used to describe the accumulation of electrons in a system, while "electric field" refers to the region around a charged object where the accumulation of electricity can be detected and measured. These terms are commonly used in physics and electrical engineering to describe the behavior and properties of electric charge.
