WebJun 8, 2024 · The movement of charged particles through a wire or other medium is called current or electricity. There is also static electricity, which results from an imbalance or separation of the positive and negative charges on an object. Static electricity is a form of electrical potential energy. An electric current is a stream of charged particles, such as electrons or ions, moving through an electrical conductor or space. It is measured as the net rate of flow of electric charge through a surface or into a control volume. The moving particles are called charge carriers, which may be one of several types of particles, depending on the conductor. In electric circuits the charge carriers ar…
