A. They are in the elements of the circuit
B. They all come from the battery where they were stored
C. They are created in the battery
D. They are created in the wires by the battery
I thought electrons were just stored in wires. I have no idea. I think its either C or D, any help would be greatly appreciated

Electrical conductor are called as such because they have free electrons in their volume which are not part of the atomic structure. The electrons just float in the wire or are locked in betwen the space of the atoms.Applied magnetic power interacts with the electron a pushes them till they collide and stop.Hence electric current what ever the electron source is motion of electrons by collisions the first electron at the end of the wire falls off,and that is the one which causes a power transfer.A battery stores power and is considered the source of electric current.If the baTTERY AND THE WIRE ARE CONSIDERED ELEMENT OF THE CIRCUIT THAN THE ANSWER IS =A

The correct answer is A. The electrons in the circuit come from the atoms of the element or elements of the wire or circuit itself. There are always some free electrons. Most wires and circuits are made of conductors (elements that have a few extra electrons in their atoms that they can easily give up) the battery provides the pressure to move these electrons out of their atoms. The electrons move in the opposite direction from where the pressure is coming and strike another atom, thus knocking another electron loose. This electron does the same thing and this keeps electrons moving in the direction of the electric pressure until it reaches the negative pole of the battery. This completes the circuit and the process continues all over again. Break the circuit anywhere and you've stopped the electrons from moving. You've halted the electric pressure.

A would be correct. Electrons come from all elements of a circuit. The battery is neither a source nor storage unit of electrons, but rather a stoarge unit of electrical potential energy.

The come from the battery. With a chemical reaction, the electrons flow from one end of the battery to the other through the circuit.
The electrons use the wires as a medium to move.

electrons are in everything, conductors have a high probability to allow them to move, in other words molecules lose and gain electrons easily in conductive material. The electrons are already present. The circuit operates, due to the potential charge difference provided by the battery.

Electrons are in all atoms, so your answer would be "A".
They are excited by the battery if you have a complete circuit. which in turn operates your device ie. light,radio,mp3,or any battery operated device.
