What is the current in a wire if 3.4 x 10^19 electrons pass by a point in this wire every 60 seconds? a) 9.1 x 10^-2 a b) 3.1 x 10^-11 a c) 1.8 x 10^-18 a d) 11 a

The current is defined as the amount of charge Q that passes through a certain point of a wire in a time :


But the charge Q flowing in the wire is just the charge of a single electron, e, times the number of electrons N:

so the current can be rewritten as


Using ,  (charge of one electron), and , we find the current:


Therefore correct answer is A).

The amount of current in this wire is equal to: A.

Given the following data:

Number of electrons = electrons.Time = 60 seconds

Scientific data:

Charge of electron =

To determine the amount of current in this wire:

First of all, we would determine the total quantity of charge by using this formula;

Q = 5.44 C

Mathematically, the quantity of charge is given by this formula:

Where:

Q is the quantity of charge.i is the current.t is the time measured in seconds.

Making I the subject of formula, we have:

Substituting the given parameters into the formula, we have;

Neptune is the eighth planet from the sun. it was the first planet to get its existence predicted by  mathematical calculations  before it was actually seen through a telescope on sept. 23, 1846. irregularities in the orbit of  uranus  led french astronomer alexis bouvard to suggest that the gravitational pull from another celestial body might be responsible. german astronomer johann galle then relied on subsequent calculations to   spot neptune via telescope. previously, astronomer galileo galilei sketched the planet, but he mistook it for a star due to its slow motion. in accordance with all the other planets seen in the sky, this new world was given a name from greek and roman mythology — neptune, the roman god of the sea.
