Electrons inherently carry a negative charge, making them synonymous with negative charge in discussions about electricity. A charged conductor, such as one with a charge of -1.0 μC, indicates an excess of electrons, specifically around 6.24 trillion electrons. This calculation is derived by dividing the total negative charge by the charge of a single electron. Understanding this relationship clarifies the distinction between negative charge and free electrons. The conversation emphasizes the fundamental nature of electrons in defining electrical charge.
