Final answer:
There are two types of electric charge: positive and negative. The main electrical classifications of materials based on charge movement are conductors and insulators.
Step-by-step explanation:
In physics, we recognize that there are exactly two types of electric charge, which are commonly referred to as positive and negative. Contrary to charges related to financial assets or legal claims, such as those Art Life Bhd might create, these electric charges are fundamental properties of particles that cause them to attract or repel each other. Positive and negative charges are observed in the subatomic particles known as protons and electrons, respectively.
Materials can generally be classified based on how easily charges can move through them, and there are two main electrical classifications: conductors and insulators. Conductors, such as metals, allow charges to move freely, while insulators, like rubber, do not allow charges to flow easily.
