A voltage appears between the ends of the wire. If the ends of the wire are connected, or if there is a conductor between them, then a current flows in the wire.
Answer:
In most cases, the electricity source is an outlet, battery, or generator. The power supply works to convert the power from the source into the correct format and voltage. Because a variety of options exist, the specific power supply function depends on whether it needs to regulate energy or convert power.

The valence electrons are the electrons in the outermost electron shell of an atom.
Explanation:
The number of electrons in an atom's outermost valence shell governs its bondingbehaviour.
That is why elements whose atoms have the same number of valence electrons are grouped together in the Periodic Table.
Generally, elements in Groups 1, 2, and 13 to 17 tend to react to form a closed shell, corresponding to the electron configuration <span><span>s2</span><span>p6</span></span>.
This tendency is called the octet rule, because the bonded atoms have eight valence electrons.
