What is the results of electrons colliding with atoms as a current flows in a material?

Let us stick on to the principle of conservation of energy. Electron being driven by the electric field gains kinetic energy. But when an electron gets into the field of the positive nucleus its potential energy is denoted with negative sign. This means that it gives out energy to the surroundings in the form of heat. So when the drifted electrons collide with the nucleus of the atoms heat is produced. This is known to be joule's heating effect.

Why it is that electron does not flow there is no current flowing?
Electrons are in random motion in a material, such that there is no resultant electron movement. Hence a material has no current flow by its own. Only the directed flow of this charge in a direction, will results in current. when we provide sufficient energy (for example by mean of applied potential difference ) the net motion of the electron gives rise to the current flow.
Why do electrons flow through a wire?
An electrical current is simply the flow of free electrons in and on the conductors. So they are a bit like water molecules in a garden hose. And like those water molecules the flow of free electrons can be physically impeded by whatever is in or on the electrical conductor. When a material is a good conductor, the atoms and molecules of that good conductor do not get in the way of the free electrons. They do not resist the flow of those electrons very much. So even with just a low voltage to push the electrons along, the flow, the current of the electrons is high. But when a material is a bod conductor, the atoms and molecules of that bad conductor do physically get in the way of those free electrons so that they cannot flow freely through the conductor. The resistance is high in a poor conductor. So it takes a relatively higher voltage to push electrons along in a bad conductor...if indeed they can be pushed at all. Some materials are so bad at conducting it's almost impossible to move those electrons along.
A material has a net charge because it?
A net charge results when an atom gains or loses electrons. If it loses electrons, it gains a positive charge, if it gains them, it gains a net negative charge.
How does a electric current flow through a circuit?
If a voltage is applied, electrons (or other charge carriers) are subjected to an attraction towards one side, and a repulsion from the opposite side. This results in the current, i.e., the flow of charge carriers.

How does friction cause insulators to become charged?
When an insulator rubs against another material, it can cause electrons to be transferred from one material to the other due to the contact and separation forces. This results in one material becoming positively charged and the other becoming negatively charged. Friction between the insulator and another material can create an imbalance of electrons on the insulator's surface, leading to the insulator becoming charged.
Where do tremors or shock waves originate?
Waves of movement are the results of the tectonic plates colliding at the focus of the earthquake, causing shock waves or tremors.
What are the results of breeding current and tree dragons in DragonVale?
Results of current and tree dragons can be mud, crystal, or seaweed dragons.
The addition of electron shells results in?
The addition of electron shells results in more shielding of electrons from the nucleus.
What action results in an ampere of current?
MOTION OF A CHARGE (1C) IN A TIME OF 1S RESULTS THE AN AMPERE OF CURRENT TO FLOW..... on a broad way I= q/t q=ne so I= ne/t so put e = charge of electron, t=1s I= 1A then u will get how many electrons are flowing to constitute the current of 1A (e= 1.66 X 10-19 (-19 is in rays to power of 10)

Gaining electrons results in what?
Becoming a negatively charged anion.
