You won't like the answer....but electrons are charge carriers and neither their speed nor their energy has much to do with what happens within an electric circuit.

Can you give an example of an energy transformation from electrical to thermal energy?
A simple electrical radiator. Electrons moving inside the resistor at high speed will collide with the "walls", therefore increasing temperature. Even a standard light bulb works like that. Electrons inide the filament (which is just a thin resistor) collide with the walls, producing both light and heat (actually, more heat than light is produced).
What is the difference between light energy and electrical energy?
Lots of differences. For example: light is a flow of electrically neutral particles (called photons), that move at the speed of light (at least, in a vacuum). Electricity is a flow of charged particles - often electrons - that move at speeds below the speed of light.
What determines an energy level?
Electron configuration is the arrangement of electrons in an atom, which is prescribed by three rules - the aufbau principle, the Pauli exclusion principle, and Hund's rule. (1) aufbau principle - States that each elcetron occupies the lowest energy orbital available. (2) Pauli exclusion principle - States that a maximum of two electrons may occupy a single atomic orbital, but omly if the electrons have opposite spins. (3) Hund's rule - States that single electrons with the same spin must occupy each equl-energy orbital before additional electrons with pposite spins can occupy the same orbitals.
How fast do electric currents move?
Yes, typically about 2/3 of the speed of light in a vacuum - that is, about 200,000 km/sec. Note that the drift speed of the electrons is only a fraction of a millimeter per second, and the random speed of electrons is faster, but still much slower than the speed of the CURRENT.Yes, typically about 2/3 of the speed of light in a vacuum - that is, about 200,000 km/sec.

What is the relationship between energy and the speed?
The kinetic energy of an object is proportional to the square of its velocity (speed). In other words, If there is a twofold increase in speed, the kinetic energy will increase by a factor of four. If there is a threefold increase in speed, the kinetic energy will increase by a factor of nine.
Why is the resistor designed in such a way that it oppose its flow of electrons?
A resistor determines the speed that electrical energy is spent, the power. Without it, the supply is spent immediately and cannot be stored.
What is the functions of resistor?
It slows down the speed of the electrons , which are all passing through the resistor

What do electrons that occupy high energy levels have more of?
They have more speed.
Your heater blower will just work on high speed?
The blower motor speed resistor is burned out. The high speed function bypasses the resistor. The speed resistor is generally located near to the blower motor.
What are some similarities of electrons?
As single elementary particles all electrons are identical; but in atoms electrons have different energy and location. The speed of electrons is also different in diverse applications.
Does electrons rely flows during current cundetion in matal?
The electrons do move - but mostly, the energy is transferred from one electron to another. The average speed of individual electrons is typically only a fraction of a millimeter per second; the current, on the other hand, has a speed of about 2/3 the speed of light in a vacuum. The current can be understood as a wave - the transfer of energy from one group of electrons to the next.
What limitation is placed in the Bohor model of the atom?
A. The number of electrons in an atomB. The electrons found only in certain energy levelsC. The size of the electronsD. The speed of the electrons
Is an electric current a movement of electrons at near the speed of light?
No. The current travels near the speed of light; the individual electrons don't. Rather, energy is transferred from one electron to the next.
Can transformers change the electrons so they work better for electric lights?
By altering the energy (speed) of electrons, a transformer may be used to ionize a gas.
What is the working of the regulator?
n electrical regulator by using resistance the output voltage is varied simultaneously the speed is varied... But to reduce the the energy loses in the resistor, electronic regulator is introduced,which uses triac to vary the output voltage by varying the firing angle.Which avoids lose of energy in resistor...
What is a braking resistor?
A braking resistor is used in motion systems where a motor in controlled by a drive. Typically, these are high-speed servomotors controlled by a servodrive. When accelerating, electrical energy is converted to a mechanical force to move a mass. When decelerating, that kinetic energy is converted (via the motor) back into electrical energy, and must go somewhere. To brake quick enough, the energy must be dumped into a power resistor, to be dissipated as heat. Read more at the link provided below.
