Question

Find current when 100 million electrons. Prove through a cross section of conductor in one micro
second.​

Answer 1

Answer:

We use the formula for current:

where - is charge that passed through a cross section of a conductor, - is time interval, -

the number of electrons, e – is charge of one electron.

2. The work is done in moving a charge A:

( ) ( )

where is a charge, is a potential at the point A, is a potential at infinity.
