Charge conservation is a fundamental principle in physics that states the total electric charge in an isolated system remains constant over time. This concept is based on the observation that charge cannot be created or destroyed; it can only be transferred from one object to another. The conservation of charge holds true for all physical processes, making it an essential principle in understanding the behavior of electrically charged particles.

To better grasp the significance of charge conservation, let's consider a simple example. Imagine two neutral objects, object A and object B, placed in close proximity to each other. When object A gains some positive charge, say one unit, it does so by acquiring an equal amount of negative charge from object B, leaving both objects with a net charge of zero. This transfer of charge showcases the conservation of charge, as the total charge in the system remains unchanged despite the redistribution.

Understanding charge conservation is crucial for comprehending the workings of various phenomena, such as the behavior of electrical circuits, the interaction between charged particles, and even the behavior of fundamental particles at the quantum level. By recognizing the principle of charge conservation, we gain a powerful tool in analyzing and predicting the behavior of electrically charged systems.
