What is the relationship between the resistance of a material and the amount of thermal energy that is released when electrons move through the conductor?

It isn't QUITE as simple as that. The relevant formula is:
(power dissipated) = (current squared) x (resistance)So, the amount of energy dissipated not only depends on the resistance, but also on the current (that's what is measured in amperes). For example, if there is no current, there will be no power dissipated.
The formula is about POWER; to get ENERGY, which is what you asked for, you need to multiply power by time.

What changes electrical energy into heat?
when electrons flow through a conductor then the material of the conductor offers resistance to excite the electrons in the conductor to release heat energy.
What affects the resistance of an electric conductor?
The material from which the conductor is made, the length of the conductor, the diameter of the conductor and the temperature of the conductor are all things that impact its resistance.
What is the difference between a electrical conductor and a electrical nonconductor?
Simply put an conductor is a material that lets free electrons flow through it. When free electrons are flowing that is called current. So an electrical conductor will have current pass through. Non-conductive material will not allow these electrons to flow and no electricity can be passed through. Good conductors have almost no resistance to electron flow.
What material has resistance between a conductor and a insulator?
The resistance between a conductor and an insulator is: Wood, fabric, and water!
Is the material inside a light bulb a conductor or resistance?
It has high resistance.
What is a conductor and a insulater?
A conductor is any material in which electrons are free to flow, whereas an insulator is any material in which the electrons are tightly bound to the molecules with which they are associated.
Why is less resistance for a conductor wire good?
Resistance in a wire restricts the movement of the electrons through the wire. This restriction transfers some of the energy contained in the electrons into the material of the wire and as this energy accumulates in the material of the wire the wire starts to heat. Therefore, there the energy that is transferred into the wire material is considered wasted because it is not available as electrical energy, which means the consumer who is using that wire is charge for the electrical energy that is waste. It the resistance is less in that conductor the consumer will save money.
Any material that will readily release electrons?
conductor
What factors contribute to the electrical resistance of a conductor?
1) What materials the conductor is made of;2) the average cross-sectional area along the length of the conductor;3) the temperature of a conductor also affects its resistance;4) the length of the conductor is also very important.Generally, the longer the conductor, the higher its resistance.Your students' course materials can probably give you a better answer than mine, or at least you'll know it is the right one.The length, the cross sectional area, temperature of conductor along with the intrinsic property called the specific resistance of the substance.
What causes resistance in electrical conductors?
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 conductor differs from an insulator in that a conductor is an?
A conductor is a material that has one or a few electrons in the outer shell of its atoms. These electrons are easily knocked loose, or are already moving about in the material. When a voltage is applied to a conductor, these electrons are repelled by the negative polarity and attracted by the positive polarity. Their movement is called "current". a conductor is a material that transports electrons and electricity can pass through it, metals are good conductors. a insulator is something that is a barrier to electrons and can not pass electricity, rubber is a good insulator.
