A current of 1 A is drawn by a filament of an electric bulb. Numberof electrons passing through a cross section of the filament in 16seconds would be roughl

To find the number of electrons passing through a cross section of the filament, we need to use the formula:

Q = It

where Q is the total charge, I is the current, and t is the time.

Given that the current I is 1 A and the time t is 16 seconds, we can substitute these values into the formula to find the total charge Q:

Q = 1 A * 16 s = 16 C

We know that the charge of one electron is approximately 1.6 x 10^-19 C. Therefore, the number of electrons n can be found by dividing the total charge Q by the charge of one electron e:

n = Q / e = 16 C / 1.6 x 10^-19 C = 1 x 10^20

Therefore, the number of electrons passing through a cross section of the filament in 16 seconds is approximately 1 x 10^20.
