electrons come from the negative terminal, then goes around the complete circuit (clockwise) and comes back to the positive terminal. hope that helps!

What form of energy flows through a copper wire connecting the two ends of battery?
Electrical Energy. When a copper wire is connected to two ends of battery, the electrons on the -ve terminal (with excess of electrons) move to +ve terminal (electron deficit terminal) to maintain an equlilbrium, hence the energy created by these movement of 'electrons' is called 'electrical' energy
What is one way you can store chemical energy.?
Energy cannot be created or destroyed, but it can be saved in various forms. One way to store it is in the form of chemical energy in a battery. When connected in a circuit, a battery can produce electricity. If you look at a battery, it will have two ends -- a positive terminal and a negative terminal. If you connect the two terminals with wire, a circuit is formed. Electrons will flow through the wire and a current of electricity is produced. Inside the battery, a reaction between the chemicals takes place. But reaction takes place only if there is a flow of electrons. Batteries can be stored for a long time and still work because the chemical process doesn't start until the electrons flow from the negative to the positive terminals through a circuit
How do microbial fuel cells work?
When an organism respires it produces electrons which are normally passed to a terminal electron acceptor. For many organisms this is oxygen. In environments where there is no oxygen, such as in sediments and in soils, organisms use different terminal electron acceptors. Common alternatives are Nitrate and Sulphate but some bacteria are known to use solid compounds as a terminal electron acceptor. There are some species of bacteria that can use iron as a terminal electron acceptor. The ability of some bacteria to reduce (that means give electrons to) iron in sediments is exploited in Microbial Fuel Cells. The microbes (bacteria) reduce an electrode (called the anode) by using it as a terminal electron acceptor as they metabolise (eat) high energy compounds such as sugars. By linking the anode to another electrode (called the cathode) you can make a circuit that electrons can flow through. Just imagine it like a battery, the anode is the negative terminal and the cathode is the positive terminal and the electrons come from the sugar, pass through the bacteria (giving it energy on the way) and are then passed to the anode.
Does a battery supply the electrons in an electric circuit?
No, is it incorrect to say that a battery produces the charges that circulate in a circuit. Some might suggest that a battery is a current source, but the battery should most properly be considered a voltage source. It generates the electromotive force (emf or voltage) that causes charges to move. (It does this through electrochemical reactions.) The charges that circulate in a circuit (which might be termed the current flow) are already in the conductor and components. All the battery does is produce the voltage (the force) to move charges. Let's look at current flow and see why things might be best looked at in the manner we've stated.Note that the way a battery moves charges is to "inject" an electron into the circuit where it is tied to the negative terminal of that battery. The electron causes one electron in the circuit at the terminal to "move over" and that will cause another electron to "move over" and so on. This will continue until the "last electron" in the circuit at the positive terminal of the battery leaves the circuit and "goes into" the battery. Current flow in the circuit is like musical chairs with electrons everywhere in the circuit "moving over a space" to cause the current flow.Having gone through all that, it should be easier to see why a battery probably should not be considered the producer of charges that circulate in a circuit. Rather, the battery is the source of the voltage that drives the charges (the current) in the circuit.
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.
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.
Does the electrons go from the battery plus to - or is it the other way around?
Yes. The electrons, which are negatively charged, are pushed away from the negative terminal, which has excess electrons, and they and flow to the positive terminal where there are less electrons.
Do electrons leave a battery through the plus terminal?
false. no
Conducor in a battery that collects or emits electrons?
In a battery, or voltaic pile, the negative terminal or wire, called the anode, emits electrons in an electrical circuit. The other terminal, called the cathode, collects electrons in an electrical circuit.
The potential difference of a battery depends on having an excess number of electrons at the negative terminal and a deficient number of electrons at the positive terminal?
That is true but not very - the excess of electrons at the negative terminal is small. The important thing is that if you place a load (radio set, light bulb etc.) on the battery the electrons flow through the load and this movement is supported by energy supplied by chemical action in the battery.
What is the positive terminal of the battery called?
It is called the positive + terminal or post, just like you list. Electrons flow for the negative - to the + terminal contrary to popular belief.Another AnswerAs electrons flow through the external circuit from anode (negative terminal) to the cathode (positive terminal) , then the answer is 'cathode'.
What form of energy flows through a copper wire connecting the two ends of battery?
Electrical Energy. When a copper wire is connected to two ends of battery, the electrons on the -ve terminal (with excess of electrons) move to +ve terminal (electron deficit terminal) to maintain an equlilbrium, hence the energy created by these movement of 'electrons' is called 'electrical' energy
What does the positive side of the battery do?
When connected to the cable which normally runs to the starter it completes the circuit. Electrons flow from the negative terminal to the positive terminal.
True or false it is impossible for the electrons in a battery to travel form the positive to negative terminal?
false
Why is it necessary that an electron returns to the positive terminal of the battery each time another electron leaves the negative terminal?
Electrons are negatively charged, and so are attracted to the positive end of a battery and repelled by the negative end. So when the battery is hooked up to something that lets the electrons flow through it, they flow from negative to positive.
What is five letter word for terminal of a cell or battery that electrons return to after losing energy in a circut?
Anode
How do you know which way the electrons travel in standard cell notation?
In an ordinary electrical cell (commonly called a battery) the electrons will travel from the -ve terminal through the circuit to the +ve terminal. [Hope I understood your question.]
