Final answer:
The conservation of electric charges states that the total electric charge in an isolated system remains constant over time. Charges can be transferred between objects, but they are neither created nor destroyed.
Examples include rubbing a balloon against your hair, and transferring charge between objects via a metal rod.
Step-by-step explanation:
The conservation of electric charges is a fundamental principle in physics that states that the total electric charge in an isolated system remains constant over time. This means that electric charges are neither created nor destroyed, but they can be transferred between objects.
For example, when you rub a balloon against your hair, the balloon becomes negatively charged due to the transfer of electrons from your hair to the balloon. This creates a static electric charge on the balloon, which causes it to stick to certain surfaces.
In another example, if you connect a metal rod to a positively charged object, some of the positive charge will transfer to the rod, neutralizing the object and distributing the charge across the system.
