A current of 1.03 A flows in a wire. How many electrons are flowing past any point in the wire per second? The charge on one electron is 1.60 10-19 C

To calculate the number of electrons flowing past any point in the wire per second, you need to determine the number of coulombs of charge passing through that point per second and then divide it by the charge on one electron.

Given:
Current (I) = 1.03 A
Charge on one electron (e) = 1.60 x 10^-19 C

The charge passing through any point in the wire per second (Q) can be calculated using the formula:
Q = I * t

Since we are interested in the number of electrons passing through the point per second, we can substitute the formula for charge (Q = I * t) into another formula:
Q = n * e

Where:
n = number of electrons passing through the point per second

Now, let's solve for n.

Q = I * t
n * e = I * t

Rearranging the equation to solve for n:

n = (I * t) / e

Since the time (t) is one second, we can simplify the equation to:

n = I / e

Substituting the given values, we have:

n = 1.03 A / (1.60 x 10^-19 C)

Calculating the result:

n ≈ 6.44 x 10^18

Therefore, approximately 6.44 x 10^18 electrons are flowing past any point in the wire per second.

To determine the number of electrons flowing past any point in the wire per second, you need to calculate the total charge passing through that point per second and then divide it by the charge on one electron.

The formula to calculate the total charge passing through a point per second is:

q = I x t

where q is the charge in coulombs (C), I is the current in amperes (A), and t is the time in seconds.

In this case, the current is 1.03 A. So, if we assume a time of 1 second:

q = 1.03 A x 1 s = 1.03 C

Now, divide the total charge by the charge on one electron:

Number of electrons = q / charge on one electron

Number of electrons = 1.03 C / (1.60 x 10^-19 C)

Finally, calculate the number of electrons:

Number of electrons = 6.44 x 10^18 electrons

Therefore, approximately 6.44 x 10^18 electrons are flowing past any point in the wire per second.
