GENERAL KNOWLEDGE

Detailed explanation-1: -The electrode which is connected to the positive terminal of the cell or battery is called the anode. The electrode which is connected to the negative terminal of the battery is called the cathode.

Detailed explanation-2: -An anode is an electrode of a device through which conventional current (positive charge) flows into the device from an external circuit, while a cathode is an electrode through which conventional current flows out of the device.

Detailed explanation-3: -The Anode is the negative or reducing electrode that releases electrons to the external circuit and oxidizes during and electrochemical reaction. The Cathode is the positive or oxidizing electrode that acquires electrons from the external circuit and is reduced during the electrochemical reaction.

Detailed explanation-4: -anode, the terminal or electrode from which electrons leave a system. In a battery or other source of direct current the anode is the negative terminal, but in a passive load it is the positive terminal.

Detailed explanation-5: -The anode of a thermionic diode is connected to the negative terminal of a battery and the cathode to its positive terminal.
