Do electrons flowing through a good conductor produce more heat than electrons flowing through a poor conductor?

No. The opposite. If by good and poor you are referring to a medium's ability to conduct electricity, then yes, a poor conductor (I suppose) would be a conductor with higher resistance than other conductors like it, although miniscule but a conductor with no resistance is a superconductor.
Resistance causes the current flow (of electrons) to have to push through against the resistance which requires electrical energy (Why superconductors don't need voltage supplies). This electrical energy is then converted into heat. Now if you mean poor as in degraded then still no. Oxidation (Rust) is resistive so a worn conductor will generate more heat than a pristine one.
The amount of heat generated by electrical resistance (in joules) is proportional the the square of the current.

∙ 12y agoAn electric current is a flow of electric charge carriers. Conductors have a great many free charge carriers to support useful values of current, but poor conductors and insulatators have relatively few and cannot support useful levels of current. So the answer is yes, current will flow through a poor conductor or insulator, but its value (expressed in microamperes) may be insignificant compared to a 'good conductor'.
It's important to understand that poor conductors / insulators do not 'block' or 'oppose' current, they simply don't have sufficient free charge carriers to support useful levels of current.

Why is Copper a good conductor and how is it's structure different from silicon and germanium?
The reason why copper is a good conductor is because there are a lot of free electrons that can carry the flowing current efficiently. These free electrons do not remain permanently associated with the copper atoms, instead they form an electron ‘cloud’ around the outside of the atom and are free to move through the solid quickly. http://web1.caryacademy.org/chemistry/rushin/StudentProjects/ElementWebSites/copper/uses_of_copper.htm
What are materials that allow electrons to move through them easily?
A conductor. Most metals are conductors-they enable electrons to move freely through them, carrying an electrical charge. Most non-metals (notably excluding graphite, an isotope of carbon) are insulators which means that they do not allow an electrical charge to be carried through them.
Why is titanium a poor conductor of thermal heat and electricity?
Actually tungsten is a great conductor of heat and electricity. Tungsten is used a light bulb filaments. If Tungsten was a poor conductor of heat and electricity the bulb in the circuit would not glow because there wouldn't be electricity passing through the circuit. Tungsten is also used as an electrode in gas tungsten arc welding. Electricity passes through the tungsten (negative) and moves to the workpiece (positive) for most applications.
Why are most metals called good conductors?
Because such metals allow electricity to flow more freely through them than it can flow through most other things (wood, for example, is a poor conductor).
Is californium a conductor or insulator?
californium is a conductor because it is metal and can carry energy through it
Which is encountered by the electrons while flowing through a conductor?
Usually resistance is encountered by electrons while flowing through a conductor.
Which of these is encountered by the electrons while flowing through a conductor?
Resistance
Current is flowing through a conductor is it charged?
No, a charged conductor is either at an abundance or lack of electrons. The moment an earth is provided, a discharge begins, which is current flowing.
Why when lightning strike it produce fire?
because of the electrons flowing through it and positive and negative electrons produce fire
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 will only produce magnetism when current is flowing through it?
Any electrical conductor only will. Ah! You're fishing for "electromagnet".
What is the materials through which electrons through a conductor?
These are metals.
How does a generators produce electricity?
. This causes electrons to move through the conductor, which is creates a flow of electricity that we can use for lighting or running our computers.
What is the name for a positively charged conductor through which electrons flow into a device?
Anode The name for a positive charge conductor through which electrons flow into a device is called the life conductor.
What happens to the electrons in a conductor when there is a potential difference between the conductor's ends?
The free electrons in a conductor will, when a difference of potential (voltage) is applied at its ends, participate in electron current flow (or just current, if you prefer). The voltage applied to the conductor will drive current through the conductor, and the free electrons will support current flow. These electrons will actually move through the conductor. As electrons are driven into one end of the conductor, the free electrons "shift over" and electrons stream out the other end of the conductor. This is the essence of current flow in conductors.
What is encountered by the electric current while flowing through a conductor?
ambot
When an electric current flows trough a long conductor each free electron move?
An electric current flowing through a long conductor has electrons moving end to end, uniformly pushing one ahead of the other. The starting and stopping of flow of electrons from end to end is essentially instant.
