The positive terminal of an electrical circuit is called the:

Explanation:
In this context, the positive terminal is identified as the anode because the electrode connected to the positive supply is the site where oxidation occurs—electrons are released from that electrode into the external circuit. By convention, the electrode at which oxidation happens is called the anode. The opposite electrode, tied to the negative terminal, is the cathode, where reduction occurs. Ground and neutral aren’t designated positive terminals; ground is a reference/safety path, and neutral is a return path in some systems. So the positive terminal is called the anode.
