Question
if the beam current in a particular TV is 50 micro A and the charge on a single electron is 1.6x10^-19 C. how many electrons hit the face of the picture tube in one second?
Answers
50*10^-6 Coulombs/s
= (electron charge)*(# of electrons/second)
Solve for # of electrons /second
= (electron charge)*(# of electrons/second)
Solve for # of electrons /second
