Capacitive coupling is a phenomenon where an electrical signal is transferred between two conductive objects through a dielectric material, without direct electrical connection. This occurs when an alternating current (AC) signal creates an electric field that influences nearby conductors, allowing energy to flow between them. This principle is commonly used in various electronic devices, such as capacitors and microphones, where it helps in transmitting signals efficiently. Capacitive coupling can also lead to unwanted interference in circuits, making it important to manage in sensitive electronic applications.
