How many pulses of current in one second?

Answer 1

1.8A is the current or I. the time is 1 second, or t. and you don't know the charge or Q. the formular is I=Q/t so you substitute the values into the equation. so 1.8=Q/1 then rearrange, so Q=1.8*1 so Q=1.8.

then you need to divide the charge by the charge of one electron which is

-1.6E-19(E is expotential so X10) so 1.8/-1.6E-19=-1.125E19 and the unit is mms-1 so the answer would be -1.125E19mms-1 i hope that is helpful =D

Answer 2

If 1 A is flowing, then 1 C (one Coulomb) of charge passes the reference point each second.

The electron's charge has a magnitude of 1.602 x 10-19 C, and therefore the number of electrons passing the reference point each second is:

1 / (1.602 x 10-19) = 6.24 x 1018

(to three significant figures).

Answer 3

1 coulomb = 1 ampere-second = 6.242 x 1018 electrons

1 ampere x 1 millisecond = (1 x 0.001) = 10-3 coulomb = 6.242 x 1015 electrons

Answer 4

Pulses of current in one second refers to frequency, which is measured in hertz (Hz). Therefore, the number of pulses in one second depends on the frequency of the current.

Answer 5

I=1.3A

e-=1.6x10^-19C

I=ne/t

n=It/e

=(1.3A X 1s)/ (1.6x10^-19)

=8.12*10^18 e-
