Show that one ampere is equivalent to a flow of 6.25xx10^(8) elementary charges per second.

To charge a body to +1 coulomb ( charge of an electron =1.6 xx 10^(-19)C )

The cathode its 8 xx 10^(14) electrons per second, when heated. When 400 V is applied to anode all the emitted electrons reach the anode. The charge on electron is 1.6 xx 10^(-19)C . The maximum anode current is

The charge equivalent to 6times10^(18) electrons is .

The charge equivalent to 6 times 10^18 electrons is

In a neon discharge tube 2.9 xx 10^(18) Ne^(+) ions move to the right each second while 1.2 xx 10^(18) eletrons move to the left per second. Electron charge is 1.6 xx 10^(-19) C . The current in the discharge tube
