How many electrons pass through a conductor in 1 min and 30s if the current is 4mA?
To calculate the number of electrons passing through a conductor, we first convert the current to coulombs per second (C/s) by multiplying 4mA by 10^-3 to get 0.004A. Then multiply this by the total seconds in 1 min and 30s (90s) to get 0.36 coulombs. Since 1 electron has a charge of 1.6 x 10^-19 coulombs, divide the total charge by the charge of one electron to find the number of electrons passing through the conductor (0.36 / 1.6 x 10^-19 ≈ 2.25 x 10^18 electrons).

How many electrons are passing through a section of a conductor per second if the current is two amperes?
In a conductor, the flow of current is due to the movement of electrons. One ampere (1 A) is equivalent to the passage of 6.242 x 10^18 electrons per second. Therefore, if the current is two amperes, the number of electrons passing through a section of the conductor per second would be 2 x 6.242 x 10^18 = 1.2484 x 10^19 electrons.
Why is iron a conductor of electricity?
Iron is a conductor of electricity because it has many free electrons that can move easily through the material. When a voltage is applied, these free electrons flow, allowing the current to pass through the iron.
How can you tell if a material is a good conductor or not?
A material is a good conductor if it allows electric current to flow through it easily due to the presence of free electrons. Metals like copper and silver are good conductors because they have many free electrons that can move easily. Insulators, on the other hand, are poor conductors because they do not have free electrons to carry current.
Electricity is the flow of which subatomic particles?
Electricity is the flow of electrons, which are negatively charged subatomic particles. When electrons move through a conductor, such as a wire, they create an electric current. This flow of electrons is what we commonly refer to as electricity.
How can you tell what a good conductor is?
A good conductor is typically a material that allows electric current to flow through it easily due to the presence of free-moving electrons. Metals such as copper and silver are examples of good conductors because they have many free electrons that can carry the current efficiently. Additionally, good conductors often have low resistance to the flow of electricity.

What happens to metals as they conduct electricity?
As metals conduct electricity, the free electrons within the metal move in response to an electric field, creating a flow of electric current. This movement of electrons allows the metal to carry and transmit electricity through it.

Why electron freely in a metal?
The term conductor is generally applied to a substance or material that has a lot of free electrons in it. The name conductor is applied because the free electrons are already there. A material does not have free electrons because it is a conductor, but is a conductor because it has a lot of free electrons. That said, let's look at what's going on. These free electrons have energies that permit them to "wander" through the conductor; they're not "locked into" the structure of the material. And when a voltage (potential difference) is applied, current flows through the conductor because the free electrons are moving. They're made to move by the applied voltage. If we take the case of a wire in a circuit, the wire is a conductor. This wire, say a copper one, has many free electrons in it, and when we apply a voltage, electrons move. The voltage forces electrons into one end of the wire, and the free electrons "shift over" and electrons emerge from the other end of the wire. This movement of free electrons in response to an applied voltage through an conductor is the essence of current flow in that conductor.
When to much current flows through a conductor?
It depends on many factors.!! Mainly it depends upon the type of the conductor. i.e., How many valance electron is there in the conductor. As many as valance electrons as much current flows through the conductor. Length of the material should be less as much as possible and the Area (i.e., Cross section) should be increased. So the conductivity will obviously increased. By sticking in to the basics Resistance of the material should be very low. For an Ideal superconductor the resistance is ZERO as we all know. So more current flows through the conductor.

Do electrons flowing through a good conductor produce more heat than electrons flowing through a poor conductor?
Yes, electrons flowing through a good conductor produce more heat than electrons flowing through a poor conductor. This is because in a good conductor, electrons can flow more easily, encountering less resistance, which results in more energy being converted to heat. In a poor conductor, where there is more resistance, less energy is converted to heat.
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.
The electric current in a medical conductor is carried by positive electrons or electrons?
The answer is electrons. I assume you mean positrons (anti-electrons) by positive electrons, and positrons and electrons go boom when they meet, so we don't see many positrons around.
Is a 2p a conductor or an insulator?
A 2p orbital does not determine whether a material is a conductor or insulator. Conductivity is determined by the number of free electrons that can move through a material. Materials with many free electrons are typically conductors, while materials with few free electrons are insulators.
