In a battery current flows from which terminal to which terminal?

Strangely there is two directions it is said to flow.
The first and wrong is conventional current that is positive to negative. WRONG. Several hundred years ago people guest
Electron current is the direction it actually goes in. This is negative to positive.

What causes current to flow from one terminal of the battery to the other?
Current flows from negative to positive. The current flows because of OHM's law. Click the link.
Why does batteries have direct current?
In direct current, the electric charges flow in the same direction, distinguishing it from alternating current (AC). current (AC). According to Wikipedia http://en.wikipedia.org/wiki/Direct_current A battery has two terminals- a positive and a negative.When a battery is in use, current flows from the positive terminal of the battery around the circuit back to the negative terminal in one direction. according to http://www.teachnet.ie/torourke/basics.htm
When electric circuit is closed no current flow through it IS the statement is correct?
yes... this is possible if a diode i connected in reverse bias with a battery and a resistor for example. A diode in reverse bias means its anode will be connected to positive terminal of the battery and its cathode to the negative terminal of the battery. In such a case, minimal current flows through the circuit which can be neglected.
How does emergency light switch work?
An emergency light switch uses a relay. A relay has an 5 terminals. The firs two terminals are connected to a flowing current (current flows when there is a normal electricity) The next 3 terminals are the common, the normally on, and normally off. One of the battery terminal is connected to the common, and the other one terminal of the battery is connected to one terminal of the light bulb(which has two terminals) then the other terminal of the light bulb is connected to the normally on terminal of the relay. When current flows to the first two mentioned terminals of the relay, the circuit of the battery and light is cut off or not connected. But when the current is off, this will switch on the normally-on terminal thus current will flow from the battery to the light bulb, that will shed light. ;) on an emergency situation. note: The normally off is not use. And may be use for some purpose.
What is the name of the circuit has current flowing in a loop from the negative battery terminal in the positive battery terminal?
its called a direct current aka DC
Does resistance depend on whether the current leaves or enters the negative terminal?
No, resistance of a wire depends only on its nature, length and area.(R=pL/A) . It is independent on whether the current leaves or enters the negative terminals. By the way, current always flows from negative terminal of battery to its positive terminal,conventional current is nothing. But this is beyond the scope of the question!
What flows through wires that are hooked to a battery?
Electrons flow through wires that are hooked to a battery. The battery's negative terminal repels the electrons, while the positive terminal attracts them.
Do batteries give off electrons to circuits?
When any conducting material is connected to provide a continuous path between the two terminals of a battery, electric current flows through it. On the microscopic level, electric current is really the flow of electrons, from the battery's negative terminal, through the conducting path, to its positive terminal.
The flow of current in electrodes is in which direction?
The ELECTRONS flow from the negative to the positive terminal. But it is considered that the electric current flows from the positive to the negative terminal.
Why do the terminals of the battery have to be connected to different poles of the light bulb for the circuit to complete in a safe manner?
The current flows from the positive terminal, along the wire, through the bulb and along the other wire back to the negative terminal.
What does it mean to source current?
the source current is the current that flows from the power source.
A resistance of 10 ohms is placed across a 9 volt battery what current flows through the battery?
No current flows through the battery. There is a current through the external circuit. I = E/R = 9/10 = 0.9 amperes.
