The current of electrons hitting the screen of a cathode ray oscilloscope is 2.0 X #10^-4#A. Determine the number of electrons that strike the screen each second. (Take charge of an electron as 1.6 X#10^-19#C).


Answer:

Q=It
=#2times10^-4A times 1#
=#2.4times10^-4C#

n=#(2times10^-4)/(1.6times10^-19)#

=#1.25times10^15# electrons
