Detailed explanation-1: -Sometimes, the electrons in an atom’s outermost shells do not have a strong force of attraction to the protons. These electrons can be pushed out of their orbits. Applying a force can make them shift from one atom to another. These shifting electrons are electricity.
Detailed explanation-2: -This force is called electromotive force, EMF, or voltage (V). Sometimes it is convenient to think of EMF as electrical pressure. In other words, it is the force that makes electrons move in a certain direction within a conductor.
Detailed explanation-3: -Conductive materials are those that can conduct electricity to a greater or lesser extent. These types of materials allow electrons to flow freely and fluidly from one point to another if they are connected to a power source.
Detailed explanation-4: -Whenever electrons are transferred between objects, neutral matter becomes charged. Three ways this can occur are referred to as conduction, polarization, and friction. Conduction occurs when there is direct contact between materials that differ in their ability to give up or accept electrons.
