The charge of an electron is -1.60x10-19 c. a current of 1 a flows in a wire carried by electrons. how many electrons pass through a cross section of the wire each second?

electrons pass through a cross section of the wire each second.

Explanation:

According to mole concept:

1 mole of an atom contains number of particles.

Given : Charge on 1 electron =

Charge on 1 mole of electrons =

To calculate the charge passed we use the equation:

where,

I = current passed = 1 A

q = total charge = ?

t = time required = 1 sec

Putting values in above equation, we get:

When 96500C of electricity is passed , the electrons passed =

1 C of electricity is passed , the electrons passed =

Hence, electrons pass through a cross section of the wire each second.

explanation:

considering the bohr theory, the type of connection that requires the transfer the answer conuldn't be right

electromagnetic shielding is the practice of reducing the electromagnetic field in a space by blocking the field with barriers made of conductive or magnetic materials. shielding is typically applied to enclosures to isolate electrical devices from their surroundings, and to cables to isolate wires from the environment through which the cable runs. electromagnetic shielding that blocks radio frequency electromagnetic radiation is also known as rf shielding.

the shielding can reduce the coupling of radio waves, electromagnetic fields and electrostatic fields. a conductive enclosure used to block electrostatic fields is also known as a faraday cage. the amount of reduction depends very much upon the material used, its thickness, the size of the shielded volume and the frequency of the fields of interest and the size, shape and orientation of apertures in a shield to an incident electromagnetic
