Question

compute the number of electrons passing per minute through an electric bulb of 60W,220V

Answer 1

A 110W bulb at 220V draws 0.5 A of current.

It means that 0.5 C of charge passes through the filament per second.

The charge on a single electron is 1.6∗10−191.6∗10−19CC

Thus the number of electrons is 3.125∗1018persecond3.125∗1018persecond

0r 3125000000000000000 electrons per second.
