Show that one ampere is equivalent to flow of `6.25xx10^(-18)` elementary electrons per second ? Charge on electron `=1.6 xx 10^(-19)C`.

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 )

An electron revolves aroung a nucleus in a circular orbit of radius 0.60Å . Find the equivalent electric current in the orbit if it completes 5.4 xx10^(15) revolutions in one second. Given charge on electrons is 1.6 xx10^(-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
