What are the two types of electrical charges?

• A. Positive and neutral.
• B. Positive and negative.
• C. Negative and neutral.
• D. Positive and resistance.

Answer: (B)

The two types of electrical charges are positive and negative. This distinction comes from the fundamental properties of electricity and atomic structure.

In an atom, protons carry a positive charge, while electrons carry a negative charge. These opposite charges at a basic level explain how electrical interactions occur. Like charges repel each other, while opposite charges attract. This principle is foundational in understanding electric forces, current flow in circuits, and the behavior of various electrical components.

Neutral charges, which were mentioned in some of the other options, refer to a state where the number of protons and electrons are equal, canceling each other's charge. Similarly, resistance is a property that opposes the flow of electric current but is not a type of charge itself. Understanding the nature of electrical charges is crucial for anyone studying electrical science as it lays the groundwork for further concepts, such as current, voltage, and circuitry.
