Mass and speed of (current) electrons

In summary, the mass of an electron is approximately 9.11 x 10^-31 kilograms. The speed of an electron affects its behavior in various ways, with high speeds exhibiting wave-like behavior and low speeds behaving more like particles. The mass and speed of electrons are inversely proportional, meaning that as the speed increases, the mass decreases. Electrons can have different speeds depending on their surroundings and can be measured using techniques such as particle accelerators and electron microscopes.

If a direct current (100 Volt) and (5 Amp.) is supplying a (500 Watt) bulb.
How many electrons (how much mass) are moving and how fast?

I am not a student, but do just need the result.

PS !
The resistance in the wire we can assume to be zero.

What is the mass of an electron?

The mass of an electron is approximately 9.11 x 10^-31 kilograms.

How does the speed of an electron affect its behavior?

The speed of an electron affects its behavior in various ways. At high speeds, electrons exhibit wave-like behavior and can pass through materials, while at lower speeds they behave more like particles and are affected by the forces of attraction from other particles.

What is the relationship between mass and speed of electrons?

The mass and speed of electrons are inversely proportional. This means that as the speed of an electron increases, its mass decreases.

Is it possible for electrons to have different speeds?

Yes, electrons can have different speeds depending on their surroundings and the forces acting upon them. In a vacuum, electrons can travel close to the speed of light, while in a material they may have significantly lower speeds due to collisions with other particles.

How are the mass and speed of electrons measured?

The mass and speed of electrons are measured using various techniques, such as particle accelerators and electron microscopes. These instruments allow scientists to observe and manipulate electrons in controlled environments to gather data on their mass and speed.
