Net charge is the overall electric charge of an object or system. It is a measure of the total amount of positive and negative charges present.
Net charge is calculated by finding the difference between the total number of protons (positive charges) and the total number of electrons (negative charges) in an object or system. The result can be either positive (more protons than electrons) or negative (more electrons than protons).
Finding net charge is important because it helps us understand the behavior of matter and the interactions between particles. It is a crucial concept in fields such as physics, chemistry, and biology.
The unit of net charge is the coulomb (C), which is equivalent to the charge of approximately 6.24 x 10^18 protons or electrons. It is a derived unit in the International System of Units (SI).
Yes, an object can have a net charge of zero if it contains equal numbers of positive and negative charges. This is known as being electrically neutral. Examples of electrically neutral objects include most everyday objects like tables, chairs, and humans.
