Charge in electrical terms is fundamentally defined as an inherent property of matter that causes it to experience a force when placed in an electromagnetic field. The correct choice states the definition of current, which is the flow of electric charge and is quantified as the amount of charge flowing per unit time.

This concept is crucial in understanding the relationship between charge and current; specifically, current (measured in amperes) is defined as the flow of charge (measured in coulombs) per second. Therefore, this definition emphasizes that charge itself is linked to the flow of electrons, and thus, understanding current elaborates on how charge behaves in an electrical context.

The other options do not accurately capture the essence of what charge is. While option A refers to current rather than charge directly, option B incorrectly links charge specifically to energy, and option D misrepresents charge as merely a count of electrons, which does not encompass the broader electromagnetic principles inherent in the definition of charge itself.
