Led which is cathode

A cathode is the electrode from which a conventional current leaves a polarized electrical device. This definition can be recalled by using the mnemonic CCD for Cathode Current Departs. A conventional current describes the direction in which positive charges move. Electrons have a negative electrical charge, so the movement of electrons is opposite to that of the conventional current flow. … Nettet7. jul. 2024 · Common Cathode RGB LED. In a common cathode RGB LED, the cathode of the internal LEDs are all connected to the external cathode lead.
