Question

Only one electron passes per second through a cross section of conducting wire. How much is the current formed?

Answer 1

Answer:

1.6×10^-19 Amp

Explanation:

According to the given question,

No. of electrons, n = 1

time, t = 1 sec

And we are asked to find current.

So we know, Q= ne

Where, Q = Total charge

e = electron charge; which is 1.6×10^-19

• So, Q = 1×1.6×10^-19

• Q = 1.6×10^-19

And we also know,

• I = Q/t

Where I = current

• So, I = 1.6×10^-19 /1

• I = 1.6×10^-19 Amp.

So 1.6×10^-19 ampere of current will flow through the conductor in 1 sec by 1 electron.
