A terminal is the point at which a conductor from a component, device or network comes to an end.[1] Terminal may also refer to an electrical connector at this endpoint, acting as the reusable interface to a conductor and creating a point where external circuits can be connected.[2][3] A terminal may simply be the end of a wire or it may be fitted with a connector or fastener.[citation needed]

Terminal symbol

A terminal strip, to which wires can be soldered

In network analysis, terminal means a point at which connections can be made to a network in theory and does not necessarily refer to any physical object. In this context, especially in older documents, it is sometimes called a pole. On circuit diagrams, terminals for external connections are denoted by empty circles.[4] They are distinguished from nodes or junctions which are entirely internal to the circuit, and are denoted by solid circles.[5]

All electrochemical cells have two terminals, referred to as the anode and cathode or positive (+) and negative (-). On many dry batteries, the positive terminal (cathode) is a protruding metal cap and the negative terminal (anode) is a flat metal disc (see Battery terminal). In a galvanic cell such as a common AA battery, electrons flow from the negative terminal to the positive terminal, while the conventional current is opposite to this.[6]

Answer:

An electrical cell is an "electrical power supply". It converts stored chemical energy into electrical potential energy, allowing a current to flow from the positive terminal to the negative one via an external circuit. The positive terminal is called a cathode and the negative terminal is called an anode. This current can be thought of as the flow of positive charges, even though it is usually electrons, which have negative charge that carry current in a copper wire circuit. Since the current is the flow of positive charge, the negative electrons flow in the opposite direction to this (conventional) current. Within the cell itself, the charge flows from the negative terminal to the positive terminal as it gains electrical energy.
