Charge Carriers

Charge carriers are particles that carry electric charge within a material, allowing for the flow of electricity. In metals, these are typically electrons, which move freely and enable conductivity. In semiconductors, both electrons and "holes" (places where an electron is missing) act as charge carriers. In electrolytes, ions carry charge. The movement of these charge carriers is essential for powering devices, transmitting signals, and enabling various technologies. Understanding charge carriers helps explain how electrical currents flow and how materials can conduct or insulate electricity.
