An anode is an electrode of a polarized electrical device through which conventional current enters the device. This contrasts with a cathode, an electrode of the device through which conventional current leaves the device. A common mnemonic is ACID, for "anode current into device". The direction of conventional current in a circuit is opposite to the direction of electron flow, so electrons flow from the anode of a galvanic cell, into an outside or external circuit connected to the cell. For example, the end of a household battery marked with a "+" is the cathode.

धनाग्र (ऐनोड / anode) उस विद्युताग्र (इलेक्ट्रोड) को कहते हैं जिससे होकर किसी वैद्युत युक्ति में विद्युत धारा प्रवेश करती है। विद्युत धारा की दिशा इलेक्ट्रॉन के प्रवाह की दिशा के विपरीत होती है।
