What type of charge do electrons carry?

• A. Positive
• B. Negative
• C. Neutral
• D. Variable

Answer: (B)

Electrons carry a negative charge, which is a fundamental property of these subatomic particles. This negative charge is one of the key characteristics that distinguishes electrons from protons, which carry a positive charge, and neutrons, which have no charge at all.

In the context of electric charge, the convention is that the negative charge of electrons is the primary mobile charge carrier in most electrical circuits. When electrons flow through a conductor, they create an electric current, which is measured in amperes. This movement of negatively charged electrons is essential for the functioning of various electrical devices and systems.

Understanding that electrons have a negative charge is crucial for grasping other concepts in electricity and magnetism, such as charge interactions, where opposite charges attract and like charges repel. This concept is foundational in fields ranging from chemistry to engineering, as it helps explain chemical bonding, circuit behavior, and many other phenomena.
